25 minutes of anaerobic pain...

So I did a local time trial this evening... that was a new experience. I prefer longer course triathlon, so going as hard as you can for "only" 10 miles was a a whole new feeling. I think I may have started off a bit too hard to say the least. My heart rate soared into the upper 170's which, for me, is extremely high on the bike. And weirdly, it stayed there (>174 or so) for most of the ride. I finished in around 25:30, but I'm sure there were some very serious bikers out there that went significantly faster than that. They do this time trial every Wednesday evening for the next 3-4 weeks, so if I can find the time to do it again, should be interesting to see if I can squeeze out a few more seconds.
