I have been running very conservatively in my vibrams.
Last week was a bit of a milestone as for the first time I replaced one of my main weekly runs with a vibram based run of the same distance. At this stage these are limited not only in distance but also intensity, so basically short easy runs only.
Today I reached another milestone as I did 11km with my vibrams today, most of which was off-road as I followed my familiar route up to Pewley hill and Newland’s Corner. With the recent rain the trails were wet and muddy though and although the vibrams have small protuberances underneath, I slipped and slid all over the place on the narrow sloping trails.
My feet and legs are still getting used to the uncushioned vibrams as my muscles and tendons strengthen and grow better accustomed to performing the shock absorbing task they were originally evolved for, but have been denied the opportunity to carry out by being constrained in the ‘technological marvel’ of running shoes we have been marketed over the last few decades!
I’m sure you can see where my affiliation now lies.
