I tried following a structured workout (AeT & ANAEROBIC POWER TEST) but between the computer and Garmin I got all confused. The laps on this are all over the place - I thought the computer was tracking that, so I stopped doing it on the Garmin - that's where the confusion came into play... I still think I did what I was supposed to, will check after I eat and give my ass a rest… i ate, and... I did manage to extrapolate the values I needed from the workout and they match the vlaues I had before pretty close. It was a tough ride, hardest port was actually the saddle on my bike. One thing is riding out on the road with that thing, another with it on the trainer. I'm gonna have to get me one of those granny gelo saddles to make sure I don't end up like I did tonight - hurting...
