Just bought this Garmin Forerunner 305 and used it twice this weekend. I had an earlier Garmin GPS unit (201) and a Polar foot pod model. This is the best tool by far. The GPS unit is much improved and it measures time, pace, distance, elevation, direction, everything. The two things it doesn't do is make you faster and make you richer. It's not cheap. But luckily my also too expensive Polar foot pod konked out so many times I got my money back and used it towards this contraption.
