WHAT PEOPLE SAY

NICOLE PALADY

⭐️⭐️⭐️⭐️

The race was great, but the lack of aid stations was definitely noticed. And the ruck was mis measured. The ruck was a 25k but after it was finished it ended up being i think 16.5 or 17.5. That last extra added mile made a huge difference in what was left with water, etc. The route was also not clearly marked so a friend got turned around.

⭐️⭐️⭐️⭐️⭐️

Huge shout out to y’all for throwing some of the best races I’ve ever done. Courses are always marked nicely and the race staff is motivating/caring when solo crewing! Only thing I could recommend for improvement is the ice bath at more races like at last years fire trail running festival! It was so nice post race! Looking forward to many races this year with Texas outlaw in prep for the 100 miler attempt in November!
