"Not perfect, but better than any other"4.5 starson by gusad1960
Pros: Size, readability, battery, PC link,
Cons: Poor GPS tracking
Summary: First of all, this is the best of what is out there today (unless you want to lug a 5 lb GPS meant to ride on the dashboard of your car).
Tremendous aid to any runner/biker. I run 5 yrs using a pedometer and one cannot expect any accuracy better than 5%. I've used the 201 for 2+ yrs/3000 miles and it is within 2% MOST of the time. There are instances where it will worse, especially in narrow streets or under tree cover (summer). I agree that it is not tremendously accurate for race day, but my results where a lot better than those reported by another reviewer (a couple of examples: 13.5 miles on a half marathon, and 6.5 miles on a 10K race). It almost ALWAYS errs on the + side. As for features, it works really well. Big display, good backlight, really watertight, training assistant. I wish Garmin would improve the gain on the GPS antenna, although they may be limited here to keep its size reasonable. The new constellation of GPS satellites that the US gov't started launching in late '05 may help get the accuracy to below 1%. The PC software is another cool thing that allows one to track all the runs & bike outings. It'd be nice if it would keep these in separate logs. Also, there are a number of third party programs that will take the Forerunner data and map it on a street or satellite map showing the path you've taken in your workout.
