Polar S720i

I just purchased a new Polar s720i watch. It can measure a bunch of things, including Heart Rate, Altitude, Temperature, Speed (it has a sensor that attaches to your bike), Cadence (optional extra sensor which I didn’t buy), Power Output (another optional extra which I didn’t buy because it costs R3500) and Calories burned. It can not only measure all that, but it can record 11 hours worth of info measured at 5 seconds intervals.

Starting tomorrow morning I’ll be training much more scientifically. And as proof of that, I’ll start posting each week’s workouts (a graph containing all the info) on my blog on Fridays.
