does anyone use a HRM during a race
Hi Does anyone use a garmin HRM during a race or swim? I've got a 301 and it says its waterproof for a short period of time but I've never tried it in the water? I wouldn't use the main unit during the swim in a race though but obviously would the chest strap as putting it on in T1 would take too long. Has anyone warn the strap during the swim?
