Summary: BAD! If you want a watch for approximate distance, spend the $150. If you want to seriously train and adjust your workouts based on the watch, you are making a big mistake. I have accurately measured/marked courses, and this watch is +/- 10%. It should be <1%. If you want to set an accurate pace, using this watch for a 7min/mile(3:03 marathon) pace, you could be "OK" with 6:18-7:42 (2:45-3:23 marathon!)!! Trainingpeaks shows me "running" through ponds.
Summary: Takes a long time to find GPS satellites. GPS does not work indoors (indoor running track, swimming laps). Software program difficult to operate for downloading information - not very clear. When battery runs out, you need to set date/time all over again. Altitude gain not accurate. Need computer (or adaptor) to charge. Large metal buckle on strap is uncomfortable when swimming. Not what I expected from Timex.
Summary: better than I expected. I really like the size and the fact that I will never have to worry about my battery going out and the hassle of sending it back to the manufacter for a new battery. I simply recharge it every two weeks.
Summary: After running with this watch for a few weeks I love it! It's just what I was looking for. I've ran with a Garmin for years, but it finally died. My only complaint about the Garmin was the touch screen/sides weren't always responsive. My FAVORITE part about the IM Run Trainer is that is has physical buttons and you can navigate while running without needing to look down. It also works really well on my bike rides even without a footpod.
