Such a great start! That's what you should remember for the future (and maybe try to figure out how to deal with heat, in case it's like this again sometime). The heat was a horrible wild card that really was unfortunate, and it's tough how your body reacted. I have felt like that before, maybe not quite as bad (no ambulances ...), but I know it's just an awful feeling. I'm glad you were able to finish, so Greg & Eric got to run, and I hope you have fully recovered.
All races are more experience, and will help you in the future.
Overall, you had a really fine WOC debut. Now take a rest, and remember the good stuff that happened.
Yes!! Learned a lot from the past week and already putting it to use tomorrow. And ofcourse gotta get ready for NAOC next week. Its a good thing its not too hot in Whitehorse ;)
