Sounds like bkool helped you out, sounds like you had to dig very very deep, did you have a strategy for refuelling and hydration ?, have you got another event to train for now?
Oh yes! Digging very deep is the only way. No real strategy for refueling and rehydration. Just try to eat warm food and drink warm liquids whenever possible but everything tastes horrible and you struggle to keep it down later in the race. No more races on the horizon but would like to beat my personal records on my local park ride.
