I recently installed the RunKeeper Free application on my iPhone 3GS. I’ve used it a couple times to track my walks around the neighborhood, as well as a few short cycling trips. Generally, the application has worked pretty well. It tracks the time and distance of each workout. Afterwards, I can view my exercise log on the RunKeeper website, which offers route maps, calories expended and other wonderful data. Last weekend, RunKeeper recorded my best workout ever.

In a feat that Lance Armstrong would have a difficult time replicating, I biked 63 miles in 23 minutes with an average speed of 161 miles per hour. Or, that’s what RunKeeper reported. The strange thing is that I’ve biked this route before and RunKeeper had given more reasonable numbers previously. I wonder if the overcast skies left RunKeeper all confused.
