Wiped out after 70 miles sounds about right. 
Everyone races with some degree of ânot readyâ. Donât believe that voice in your head that everyone else has had perfect preparation leading up to the event. Everyone is bringing somethingâtraining has been interrupted, life has been stressful, barely slept the night before, mechanical issues, etc.
Go through your last race objectively and learn what you can to make the next one betterâbetter pacing, nutrition, hydration, etc. Then youâll have another data point to make the next next race better.
