I just finished a 10.0km cycle that lasted about 0hh:30mm:0ss !
Super excited about this, despite not having speed / cadence andpower sensors (yet).
30 minute ride. Couldn't measure distance, but I think 10k is conservative -- considering how tired I was and how hard I was sweating. Had to peel the shirt off after 10minutes, and then quickly grab a sweat towel for under the bike after about 17.
Gotta remember to pace myself next time. Also, to grab new batteries for my HRM. Looking forward to doing some cycling!
