In my last update I detailed that I had gone back to endurance training as all the hills and speedwork of the spring had toppled my aerobic base. It was somewhat disappointing but also necessary if I’m to sort out my 800m. I now realise I’m done for this year and it’s going to be a winter of building endurance and stamina. The introduction of hills and sprints was great fun but also introduced way too much naturally anaerobic fast-twitch muscle. As I haven’t been near these areas in years, things toppled quickly. Hopefully by next winter, my base will be bigger and I’ll be able to handle the anaerobic side better.
Having restarted endurance training in early July I found I wasn’t making much progress; then in early August I realised I was beginning to get aches and pains of the sort when you’re training too anaerobically. I had to reset AGAIN. My focus became to ensure I set off on runs at a slower pace and built up to my aerobic limits. That reset did the trick as the pains dissipated and the endurance began to build. Even so I was still a good 30+ secs/mile down on where I was back in March. It was a surprise to me how easy it is undo everything.
Mid-August I did an all-out parkrun at Poole and clocked 20:25. Quicker than running there at Easter (20:40) but slower than last Christmas (20:11). I cannot tell you how frustrated I am feeling at not being able to get back under twenty minutes. Another parkrun at Sandhurst Memorial parkrun in late September was even worse at 20:48 but it’s a tougher course and my legs were fatigued so that didn’t concern me.
I’ve entered a couple of 10Ks – Boscombe on Nov 27 and Christchurch two weeks later. I’ve gone back to using the training system I used on my only ever sub-40 run back in 2015. Controlled threshold work on a Tuesday, a Steady run on Fridays and a long run on Sunday. This is the same as I was doing in February and March this year.
My plan is to do intervals at Threshold pace (6:50/mile) for three weeks, then up the pace to 6:40 for three weeks and again to 6:30 which will take me through to the end of October. After that I’m going to do shorter intervals at 5K and 10K pace which will hopefully see me breaking forty minutes again. It’s an aggressive schedule but so far the body has been holding up.
Endurance-wise it took me until mid-September to get back to where I was in February. That said, my fasted Sunday morning long runs have all been coming in at a decent pace, usually sub-8 average for 12-miles, no stops. For whatever reason, I seem to be running these quicker than in February.
Possibly some of the drop off I’ve been experiencing is down to a change in running form. Since last October I’ve been working on my form using drills at least once per week and somewhere around late June, combined with the sprints I was doing, I began to feel I was running differently. Less hip rotation and more power from the glutes. Of course, using muscles that have never been involved in my running, meant they needed to be trained and quite possibly they had a lower lactate threshold due to this. Whatever it is, the form change is beginning to feel powerful at times and I just have to keep working at it.
Behind the scenes I’ve been wondering about whether I’m cut out for training like this. For all the miles and effort, I’ve put in over the years; my improvements have been sporadic. I’ve decided this winter will be the acid test. Hopefully when spring arrives next April, I will see a decent improvement in my half marathon time. If I don’t then I’m scrapping the endurance focus and putting my training time into working on speed and to see whether I can get my 200/400 times down, even if it’s at the expense of longer distances.
I’m going to give it a fair crack of the whip and train the best way I know how to. The one sticking point is I entered the London Marathon ballot yesterday not realising the race is in six months’ time (April). If this were to be the year I get a place then my training would have to look at lengthening my long run out to twenty miles. Even so I’d expect the training I’ve got planned, to fit in well with how I would need to train. We’ll see when the ballot results are announced at the end of October. I’m currently doing just shy of fifty miles per week and have been for the past two years so the base is there for whichever direction I need to go.
