There is no question in my mind that this plan will make me faster this summer. How much faster I don't know but this is definitely the type of stuff I've been missing for the last few years. When I lived in Camden I was surrounded by like minded folks and had no trouble finding frisky road and mountain bike rides where I got more than my share of intervals and hard efforts so real focused training wasn't necessary for me then. Fast forward a few year, job change, child and no riding buddies living nearby and focus is just a wee bit more important.
Saw this pic the other day from a dude near Portland who made toe warmers for his bike shoes out of old tubes. Pretty clever. Not sure about his stitching though.
