Hi BriGuy. It sounds to me like it might be worth starting a bit more conservative in the early miles this year and see what you have in the tank on the final high altitude section. The race strategy of going really hard at lower altitude still sounds like it will leave you too tired and blown to race your best race at high altitude. The best thing you can do is work on your fitness the best you can in your preparation for the event and then to run a smart race. Just my two cents. Good luck! ~Mike Foote
