Which Garmin, if any.

The 405 has a lower battery life, quoted as up to 8 hours. My 205 (the 305 without the heartrate monitor) lasted for 12 and a half hours on a long rainy race last December. So if you like long distance challenges you should perhaps consider that. I find it great for checking your pace and uploading details after training.

I have the a Timex body link system that has user replaceable batterie,s a single AA battery lasts for twelve hours, therefore after about eleven hours i pop a new one in and carry on (I am partial to a bit of Ultra Running), coupled with the data recorder this gives the facility to download runs to the puter, all the figures shown Altitude etc seem pretty accurate when compared with spot heights and known distances etc.

You can`t (as far as i know) download routes to it but then i don`t want to after all that`s what a map and compass is for.

Used in conjunction with Tracklogs Timex bodylink does it all including HR wet or dry
