Underwear of Fortitude

So, I got out today for some of these SST Intervals. It definitely required me to HTFU and I could have used some of this so called underwear of fortitute that Goats was talking about. I did man up for 75 min. of riding though by the end I was having trouble braking and shifting because my hands were so called. Also, I had the joy of being thirsty since the water froze in the nozzle of my bottle. All in all I did feel awfully manly when I was done my workout. Hopefully it will be a tad warmer for Saturday's long ride.
