At a conference and elected, foolishly perhaps, to not bring my pedals and shoes. Road a LifeFitness bike -- embarrassed to say. 10' warmup, then dialed it in, according to LF bike system, for 225w for 60'. I'm not sure what the actual wattage was, assuming LF is not that accurate. However, I felt like I was gutting it out most of the way. That may have been a function of not being in my usual seating position and riding in sneakers rather than cleats. I don't ride with a heartrate monitor, but the LF had a measurement system. Again, accuracy may be questionable. Started out in upper 150s and lower 160s; at about 20' in, system started showing 170s and then 40' in, system showed in the 180s, ending up in 185ish for last 5'-8'. At the least, I'm hoping this workout minimizes loss until I get back to my bike.

While I train based on power, I might play around with a heartrate monitor in the future.
