"I am not an expert on these things, but the Garmin software is pretty rubbish, someone on here recommended downloading "sportstracks" to my pc, which is ace, and free!"
*waves at RP*
Unfortunately though, I'm pretty sure Sportstrack doesn't support Macs, only Windows PCs. There must be other mac users out there though so hopefully someone will recommend an lternative for you as the Garmin Training Center is a bit naff.
But yeah the 205 is excellent and great value for money. Like you YL, I got mine while injured so I haven't really made the most of it yet, I'm itching to get out there and use it properly.
