They say the definition of insanity is doing the same thing again and expecting different results and it’s probably a good thing to keep in mind when planning your training for a race. I’m marathon PB chasing again with Milton Keynes marathon on 2nd May 8 weeks away now and a pretty aggressive time goal in mind. Currently my PB is 3 hours 26 minutes which I set at the 2014 Yorkshire marathon. I was on track to beat it last year again at the Yorkshire marathon but the fact that I’d spent the year triathlon training became very apparent at 20 miles as I hit the wall pretty hard.
But I know I’m capable of faster if I can get a solid block of training in and stay healthy. However there is no point just blindly following the same plan as for the other marathons I’ve done and expecting to be somehow in better shape. Training has to be an evolution where you learn race by race what works for you and what doesn’t, but also what you can learn from how others approach their training. Make a small change each time and review the impact it has, what is the result in the race and how do you feel.
