Eilish’s low mileage

Scotland’s Eilish McColgan is the current golden girl of British Athletics. This year she has set distance records, the first occurred in February when she broke Paula Radcliffe’s British half marathon record by 21 seconds in 1:06:26. Then in May, she ran 30:19 to take Radcliffe’s 10K road record and on Monday (June 6th), she ran this time again on the track in Hengelo, Netherlands to set a Scottish record.

The McColgan name is not unfamiliar to followers of running. Her mother, Liz, was the World Champion in 1991 at the 10,000m having already been Commonwealth Games champion in 1986 and 1990 and silver medal winner at the 1988 Seoul Olympics. When she moved up to the marathon distance she won New York (1991), Tokyo (1992) and London (1996) marathons. Eilish’s father, Peter McColgan, was also a talented distance runner who competed for Northern Ireland in the 3,000m steeplechase and 5,000m at the Edinburgh Commonwealth games as well as for Great Britain in the steeplechase at the 1991 World Championships. What a pedigree for Eilish to have!

Not only does she have the genetic advantage but Eilish is also part of a generation of successful female Scottish distance runners. Laura Muir has been the most successful gaining a silver medal at last year’s Tokyo Olympics where she set a British record for the 1,500m in a time of 3:54.50  In 2012, Lynsey Sharp was European champion and competed at the London Olympics in the 800m. She followed this up four years later setting a Scottish record of 1:57.69 while finishing 6th in the Rio Olympic final.


A recent BBC article detailed that this year’s success is down to Eilish undertaking a reduced training load that Liz had to be persuaded would be in Eilish’s best interest. Liz had been running as much as 140 miles per week in her marathon prime.

But this highlights the event differences. Liz was always a long distance runner doing 10,000m and marathons. Following in her dad’s footsteps, Eilish competed in the 3,000m steeplechase for Great Britain at the London Olympics and then the 5,000m in Rio. It wasn’t until 2018 (when she 28 years old) that she began racing longer distances winning the ten mile Great South Run in 54:43. Roll on three years to the Tokyo Olympics and Eilish competed in both the 5,000 and 10,000m. Looking back at her Personal Bests, her time for 800m is 2:07.8 – over ten seconds slower than Lynsey Sharp and her mile is 4:00.97 which is five seconds slower than Muir. It’s clear that although Eilish competes in middle distance races, she lacks the top-end speed to be winner against the best and like her parents is better suited to the longer distances.

So it’s surprising when she talks in the article about how her training increased from 20, 30, 40, 50 miles per week and has only been operating at 65-70 over the last year and a half to two years. It’s not unusual for a world class 800m runner to operate on as little as forty miles per week but Eilish isn’t one. Typically world class 5,000 – 10,00m runners train between 70-100mpw. Given the recent increase in training mileage, it’s no surprise that when Eilish returned to the Great South run last October she was four minutes quicker than three years ago.

There’s no doubt decent mileage is critical to distance running success and Eilish’s approach of starting on low mileage and building up is a good one to follow but far too many runners simply aren’t doing enough mileage to support longterm improvement. Getting the balance right is important and, as Eilish shows, great results can be achieved off moderate mileage.

While I don’t wish to take anything away from how hard I’m sure she’s working in training, it should be noted many road and track records have been broken over the past couple of years due to the innovation of carbon plates in shoes. I am slightly sceptical Eilish would have been breaking Radcliffe’s records without them (at least in the near future); but many past records have been broken due to now-forgotten reasons outside of better athletic prowess. And in the longer term, unless the IAAF backtracks on the use of carbon plates, these records will become the new standard. All power to her – she’s still the best we’ve seen in a long time.

Whatever the reason, I have no doubt Eilish McColgan is going to go on to greater things as she gets the benefit of higher mileages and moves up to the longer distances permanently. At 31 years old, she has potential for another Olympic cycle in her and maybe more. I’m sure she will be looking to emulate her mother by taking on the London Marathon and other Majors.


Bonus content – Eilish is listed in Wikipedia at 1.80m (5’11). In my article on stride length I observed her cadence averaging 172 steps per minute giving her a stride length of 1.97m. It’s easy to think this is because she is tall and to an extent it is. But, as I also pointed out, Eliud Kipchoge (1.67m – 5’6”) has a stride length of almost two metres – about 15% greater than his height.

A quick look back at Paula Radcliffe running mile 5 of her record-setting 2003 London Marathon shows her running with a stride length of 1.67m (186-88 cadence) when she is 1.73m tall (5’8”). It’s a decent stride but it’s shorter than she is!

Olympic thoughts – Fast women

Tuesday afternoon, day eleven of the 2021 Tokyo Olympics, gave me an opportunity to look at world-class 800m running. It was the final of the women’s competition and from a British perspective there was huge interest. Three women making the final brought back memories of the 1980-84 Olympics when British men ruled middle distance running with Seb Coe, Steve Ovett, Steve Cram and Peter Elliott at the top of their game.

Racing two laps of the track, beginning in lanes with a standing start, runners break at the end of the first bend so that by the 200m mark they’re running together. I’d estimate the time for the first 200m was 27.7 seconds, the next 200 was a relatively slow 30.12s to give a first lap of 57.82s. The second lap was 57.39s (29.33s + 28.06s) for a winning time of 1:55.21

The race was won by USA’s 19-year-old Athing Mu and she is something of a sensation, as is silver medallist Keely Hodgkinson who is the same age. There’s a possibility they could be pushing each other to faster times for the next decade. There was almost a bronze medal for Britain’s Jemma Reekie but she was beaten on the line by Raevyn Rogers; and Britain’s third runner Alexandra Bell finished 7th out of eight.

This was one of the faster 800m finals but they’re usually won in the 1:55-57 range. From what I’ve learned about running the 800 the first lap is typically faster with the second about two seconds slower; but today was a negative split. The slower second 200m was the culprit and would have been part of Mu’s gameplan as she has run 49.57sec for the 400m. She would have been confident that if she could be leading at the bell, she’d be able to outpace the rest of the field over the second lap. Consequently she took the lead as the pack formed on the back straight of the first lap and then imperceptibly slowed the pace. She never relinquished first place and went on to win by two-thirds of a second which is huge at this level.


There is nothing slow about these women. The pace of the winning time is 3:52/mile (2:24/km) with the average per 200m being 28.8 secs. If they could do a parkrun at this pace, they’d be done in twelve minutes. But remember, as I wrote in my article on True Speed, top speed is a lot higher.

As it happened the women’s 800m final was followed twenty-five minutes later by the women’s 200m final and gives us a good chance to compare. Having already won the 100m title with the 2nd fastest time in history, Elaine Thompson-Herah was now going for a “double double”. She didn’t disappoint as she went on to run the 2nd fastest 200m time in history at 21.53s – that’s six seconds quicker than the fastest 800m split.

By comparison, the PBs of the three British women for 200m aren’t close. Alexandra Bell ran 25.74s in 2016, Keely Hodgkinson ran 26.5s in 2018 and Jemma Reekie a wind-assisted 27.3s in 2015. These times are not poor by the standards of the rest of us but, as you can see, they’re a long way off being close to competitive over a sprint distance. There’s a genetic element to what event you’re best suited to, but also note how the longer the distance you run, the more you trade off speed for endurance. Mu’s two laps of fifty-seven seconds were significantly slower than her 400m ability.

Lessons in marathon training

Imagine running your first marathon in 2hr41?  Imagine doing it off less than three months of training? Most people would be pleased with that, but now imagine you were already a great endurance athlete used to training thirty hours every week. This is Gwen Jorgensen’s story.

Graduating to work as a tax accountant in 2009, Gwen Jorgensen was talked into becoming a triathlete by USA Triathlon. She’d been a runner and swimmer through college so only needed to add the cycling skills to enter her first triathlon a year later. She was good enough to finish with elite status.  Two years later, she competed for the USA at the London Olympics coming in 38th after getting a flat tyre in the cycling section. In the following years Gwen became one of the world’s premier female triathletes, being crowned the winner of the ITU’s World Series in 2014 and 2015.

This lined her up as the favourite for the 2016 Rio Olympics. Like the World Series events, the Olympics are a 1.5km swim (taking around twenty minutes), a 40km cycle (1hr) and a 10K run (thirty-five minutes). This is about a quarter of the more famous Ironman triathlons.

In the six months prior to Rio, Jorgensen logged 137 swims, 110 rides and 171 runs. With running being her strength she’s often able to start the run, which is the last part of a triathlon, behind opponents and catch them. She was generally recognised as the fastest runner on the women’s circuit and in Rio ran 34:09 for 10K on her way to taking the gold.

On her way to gold in Rio

Having claimed the Olympic title, Gwen then threw out a curveball, she was going to run the New York Marathon three months later. More accurately she was going to do it in seventy-eight days’ time. She won the Rio gold on 20th August and the New York Marathon was being held on November 6th giving her just twelve weeks and one day to train.

As we now know she ran 2:41:01 to finish 14th and by her own admission she wasn’t happy with that time. Running the NYC marathon was to be the first step towards her goal of winning the (now-cancelled) 2020 Tokyo women’s marathon. The fastest women in the world are running sub-2:20 and in New York she set out with the leaders at 5:40/mile, managing to stay with them for the first five miles before dropping back and finishing the last two miles at seven minute mile pace. The graph below highlights how her performance dropped away in the second half.

Her seventy-eight days of training were less than ideal. She still fitted in triathlon events which meant continuing to train for those and her running mileage came in at fifty miles per week. She’d never run further than ten miles before and with the limited time available, her longest training run was sixteen miles. Another aspect of her training that was less than ideal was she trained off-road which was unlike the tarmac surfaces she encountered in New York.

Gwen’s NYC splits in parkrun terms – a noticeable drop in the second half

So what are the lessons we can learn from this performance? To me, the notable (and somewhat obvious) thing is that even though Gwen never ran longer than sixteen miles in training for her first marathon; her pace was high from the beginning and she was able to get to the end still running. She didn’t end up walking because she has a huge base of fitness from her triathlon training.

On the other hand, her triathlon training wasn’t specific enough to allow her to continue her starting pace and see it all the way through. If you want to get the most out of training then running is going to be better for your marathon than cross-training.


Training off-road didn’t work for Gwen as the tarmac in New York was tough on her legs – she wasn’t accustomed to it. Often elite runners and physios recommend running on softer surfaces to avoid inflicting damage. But I believe this is advice better suited to those running higher mileage. Gwen went from running 30-40 miles per week to 40-50 – it’s not a huge increase.

Also with specificity I’ve known people training for London who do their long Sunday runs over the hilly Purbecks. While it’s nice to get out in the peace and quiet, hills are one thing London doesn’t feature – it’s a flat course other than a slight downhill in the opening miles. Hill training has its place in a training plan as a workout but combining that with a long run is adding unnecessary stress especially for slower runners.


While Gwen is not the first runner I’ve seen who records decent times in half or full marathons off less than perfect training. I’ve seen guys run sub 1hr30 half marathons with barely any long distance training because they’ve got the speed over shorter distances. I’ve done it myself – I ran a 3hr41 marathon with only six weeks where I ran more than thirty miles but I was already running twenty-one minutes for 5K.

This is really key. First you have to be able to run fast, or more specifically you have to have a high lactate threshold which is the result of combining speed and endurance. After that it’s about how much pain you’re willing to suffer as your body fatigues and slows down. Trying to run a marathon on fifty miles per week, in less than three months, with nothing longer than a sixteen mile run wasn’t enough to stop Gwen’s pace dropping in the final miles. I experienced the same on my marathon, I went from running 8:15/mile to 9min/mile in the last six miles.

If you’ve read my post on the 20-mile myth you may wonder, doesn’t this conflict with the Hansons’ idea of not running longer than sixteen miles in training? Superficially it does, but the plans in their book are not aimed at elite runners like Gwen. Their elite plans do more weekly mileage, over a longer training period and go out to twenty miles. The underlying principle of their system is to avoid overdoing long runs if you can’t complete them in two-and-a-half to three hours maximum. I believe that’s good advice.

Chicago 2018 marathon – the wet and windy city

A key driver for Gwen’s change from triathlon to running marathons was a desire to start a family. Typical triathlon training is thirty hours per week with three session per day. Some days that includes a three hour bike ride which, when you add in early morning runs, mid-morning swims, eating and changing is likely too much, although not impossible, to also do justice to raising a baby. Any parent will tell you it’s hard enough as it is. By comparison an elite marathon runner typically trains for thirty to forty-five minutes in the morning straight out of bed and then another longer session in the evening. With a supportive husband, it’s much more manageable.


However things haven’t worked out in the marathon world for Gwen. Her best marathon is 2:36 in Chicago in 2018, which puts her well down the list of American women running the marathon. It’s a time that wasn’t going to be anywhere near the gold medal in Tokyo, so in late 2019 she decided to switch to focusing on the 5,000 or 10,000 metres. Her times are still struggling to be world-class but it’s clear that while she was great at Olympic-distance triathlon she hasn’t turned out be the endurance monster many expected.

Come this autumn we’ll see how all that training has worked out for her with the postponed Tokyo Olympics. Will she even be there? In my opinion, whichever way you look at it she’s had an enjoyably challenging decade. She began it working sixty-plus hour weeks as an accountant which by all accounts (pun intended) she enjoyed. She then became less cerebral, pushing herself physically and competing in two Olympics, winning gold in one. As a triathlete she travelled around the world for the World Series events and at one stage seemed unbeatable with thirteen consecutive wins, then as the joy of parenthood beckoned she took on a new challenge and all that entails. Whatever happens I’d sum that up as living life to the max.
