I ran a half-marathon last week and noticed that my Surge tracked me about .25 miles more than the actual race. GPS was on the full time and set at the start point. I was bit dissapointed that it was not more accurate, especially during the later part of the race. Is this to be expected? One of the reasons I use the surge is for accurate GPS tracking for training and speed work.
Keep in mind, GPS, even higher end units in cars lose satellite lock under certain conditions. What conditions? Conditions like heavy cloud cover, tall buildings, mountains, and trees with heavy foliage. I've run about 2,500 miles over the last 17+ months with my Surge; sunny winter days having virtually always spot on accuracy and cloudy days in the summer having accuracy isses; I'd say maybe only 90% accurate. That said, I run on trails with tree cover so dense in the summer time I cannot see the sun at high noon.
