I love my Polar F60. I bought it to track my fitness on hikes and runs while on a trip in southwest Utah. And with it, I bought the Polar G1 GPS Speed and Distance Sensor. Alas. The shallowest of canyons had it flummoxed; the most unthreatening cliffs stymied it. On a given hike (or run) I would get mileages from 2.1 to 8.5 miles off from the established distances.
Coming home to New York City, I fared no better. Testing the G1 on daily Central Park runs of (tested) 3.7 miles, I got readings from 2.2 to 6 miles. (And according to the G1, I was running 12.3 miles per hour at my MAX - possible for some, perhaps, but not for me.) Pretty useless. Apparently the "four satellites" that are accessed need to be directly overhead.
I'm going to try the foot pod. Until I move to a Plains state.Get more detail about Polar G1 GPS Speed and Distance Sensor.
