My weapon of choice was the Concubine with her 4 week old suspension fork. i can definitely say that my hands and forearms still took a beating . But nothing like it could have been if I had gone completely rigid.
Sadly I got to wrapped up in race mode and forgot to pace myself. One needs to keep in mind at all times the distance. This meaning 60 km is along way and muscling to many hills in the wrong gear can screw up your race.
At the 40 km point the outside tendons on my knees basically locked up. So climbing was a chore. Took way longer to finish due to this. But I learned a lesson, don't go to hard.
The decision has been made that for next year I will be doing only the 30km distance,
