Here we are in July with an array of sports to choose from. Football’s European Championships, Wimbledon, the Olympics starting on the 23rd and three weeks of the Tour de France. It’s only in recent years I’ve got into watching the Tour which is mostly a procession through beautiful French countryside until a final sprint for the line in the last kilometre of a 150-250km race. Occasionally they throw in a short time trial of 30km and of course there are the gruelling climbs of the mountain stages in the Pyrenees and Alps.
With ITV having over four hours live coverage to get through, the adverts are frequently interrupted by some excellent commentary by Ned Boulting and David Millar. They’re joined from time to time by Chris Boardman, who won gold at the Barcelona Olympics at a time when British cycling wasn’t that good. Nicknamed “The Professor” because he’s studied the details, Boardman brings great technical analysis to any broadcast discussing the build of bikes, aerodynamics, streamlined skinsuits, nutrition and tactics among other things. While I’m never going to be a cyclist, I enjoy listening and learning what I can from watching the Tour.
One of the things I picked up last year was that “fat burns in the light of a carbohydrate flame”. This is a saying which relates to needing some carbohydrates ingested to kickstart the process of fat-burning. Specifically Boardman stated riders will eat 20g of carbohydrate before going out on an early morning ride otherwise they’re burning through their glycogen stores. Certainly I’ve always found my heart-rate is lower (which suggests better fat-burning) after I’ve had breakfast.
I tried experimenting with eating two digestive biscuits before setting out on my long runs. I’d put two on my bedside table ready for the morning then, on waking I’d immediately eat them before getting up, getting my kit on and going straight out for my run. I never saw any notable difference when I did this so I’ve returned to running fasted but having a decent breakfast definitely helps on my workout or race days.
If you want to try it the information about grams of carbohydrates is usually there on the side of the box or packet so take a look. A couple of Weetabix is my go-to breakfast. Not too heavy and the milk helps with hydration.
The other thing I learned is that even when the Tour schedules a rest day, which are the two Mondays in this year’s three week schedule, the riders still go out on it for a two-hour ride. I could barely believe this when I first heard it. After all when you consider the riders are riding hard for the better part of 3,500km (2,200 miles), you’d think they’d jump at the chance of a day off. But, without it, I suppose they’d be almost forty-eight hours without riding.
A little closer inspection of riders’ data shows their rest day ‘recovery rides’ tend to be closer to an hour, maybe stretching out towards ninety minutes. On tour days they’re riding at an average of 40km/h with an average power of over 300W (with the ability to sprint at over 1000W); whereas a recovery day is closer to 25km/h with only 90-130W of effort being put in. It really is an exercise in keeping the legs turning over, flushing out any waste products and providing stimulus for hormonal and nutrient delivery. Unlike runners where the body’s muscular-skeletal system takes a pounding with each step, it’s much easier to cycle for over an hour without any detrimental effect. Nonetheless runners can still use recovery runs as a way to trigger recovery as well as maintain lower aerobic fitness.
