From the joy of finishing to the tough moments — read what runners wrote themselves.
“Honestly, I needed to run and talk with someone to distract me from my foot pain.”At Rockin' Rockwoods 53km, the runner endured rough descents and foot pain, chatting with others and changing socks. Food and encouragement at the last aid station restored their energy for an 8 hour 32 minute 29 second finish.
“It was nice to have someone to talk with at the start to keep my mind occupied and help me focus on staying slow.”At Rockin' Rockwoods 53km, a leaking hydration bladder and late stomach trouble led the runner to alternate walking and jogging. They gave their remaining energy on the final climb to finish their first ultra in 8 hours 57 minutes 10 seconds.
