Just minutes ago the CEO of Boston-based FitnessKeeper, which makes an iPhone run-tracking application called RunKeeper, crossed the finish line of the Boston Marathon with a very respectable time of 3:55:07. Not bad for someone wearing a lycra iPhone costume. He placed 14,217th in a field of more than 26,000. perhaps Jason Jacobs’ foot injury wasn’t quite as bad as he was suggesting last week.

Runkeeper is an iPhone app that allows you to record the times that you have run, how fast, and where. So far it’s only been a free, ad-supported app. Now Runkeeper is introducing its first ‘pro-only’ feature: audio cues that read out loud the details of your Runkeeper session at set intervals.
