From Sebastian to Ft Pierce. Worx Grate had trouble hooking up so the most I was able to squeeze out of it in this water was about 60. After the jumping, I rode the 30 miles hard and only stopped twice to wait for people to catch up. My legs are the only thing sore. My back and severely damaged neck felt no pain. And to be honest, I probably don't even need to stand up in the slightest. I know the springs aren't for everyone, but they sure do work for me. I will post a full speed version of the high speed runs soon. Enjoy!
