TESTIMONIALS
This race was amazing. first, i never thought i could do it…..and doing it was so much easier than i imagined only because of your staff and volunteers. when i could not think, your volunteers thought for me. when i could not eat, your volunteers helped to guide food to my mouth! also, the course was so well marked, which was fantastic for me…..i am so directional challenged. kudos. i’ll be back next year (NOT something i said to myself at mile 35 in the midst of a bonk), for sure, if only to better my time.

Thanks for putting on a great race. At no point did I feel lost or questioning what direction to go. Aid stations were perfect. Best race I have ever done.

Thank you! It was my first 100 mile race and I couldn’t have been more pleased with the support and the course. It was definitely challenging, but fun, too. Days before the race, I was thinking that I may not make it, but the spacing of the aid stations was perfect and very motivating to keep pushing forward. I know that you have no control over the race registrations, but I couldn’t have asked for a better crowd of racers. Everyone is so supportive of each other. The swag items are awesome, too. Thanks for having women specific t-shirts. I’ll actually wear this one!
