I hadn’t done a 5k at Bushy Park for a while, at least not properly. So today I tried to run somewhere close to PB territory. The idea then was to jump straight onto my bike and pedal like a nutter to see if I cramp. The theory being that as I’ve been doing quite a bit of high intensity brick training then I shouldn’t cramp. (Search for EAMC on the net for more on Exercise Associated Muscle Cramp).
Good news: Didn’t get cramp
Bad news: 45 secs shy of a PB, not even duathlon race pace. Fell off my bike in the car park whilst fiddling with my watch. Felt awful with a headache in the morning. Bed at 1am and wasn’t wearing my go-faster shoes. First K was something like 3:30.
Good news: Still a bit of time left to get the speed up before Gijon.
