I have a garmin forerunner
201...it's rechargeable and cost on ebay $125, now they have a 101 model for
$100 +/- You buy the batteries for it...the 201 holds it's battery power
15 hours...has software to download and log your workouts, holds info
indefinitely. And has a velcro band,fits on wrist, through the vent holes
in your helmet..take a look at them on ebay...search gps, you can be specific
and ask for gamin forerunner 201 or 101...walmart carries them too.
