Interested to now what sort of effort you put in when you race and how you manage your energy resources.
I'm going to taking part in my first mountain bike season racing in the Gorrick Series and Southern XC in the Vet category so races will be around 1 - 1.5hrs depending on how good/ crap I am.
Do you all just go balls out for the duration similar to cyclocross or do you start off steady and try and go harder towards the end of the race? If you use a HRM, do you try and stay in a certain zone if possible? Finally, how do your legs fell throughout the race, is there a constant feel of lactate build up in you thighs or does that kick in towards to end of the race when energy levels are low?
All view greatly appreciated as always.
