I decided to try out the Vibram FFs today at the gym on the TM. My plan was to run 4 miles at Doone's mp (8:35) at 2% incline. Near the end of the second mile one of the seams on my VFFs started rubbing my foot wrong, so I decided that was a sign to call it a day. I hopped on the stationary bike and road for 30 more minutes.
I won't run tomorrow and then Satruday I plan on meeting up with Doone for the end of her 22 miler. I'm just trying to decide how far I should run with her.
