Sara Santiago wrote a great little post (a love letter, she calls it) last week about dailymile. For those not familiar with dailymile, it’s essentially an unbranded descendant of the groundbreaking Nike+ site created by R/GA a few years back. dailymile has taken the concept a bit further, allowing not only runners, but anyone actively training (cycling, swimming, strength-training) the ability to track their efforts and share it with other members of the community.

It’s amazing how well digital has connected the dots for runners, but that’s always a matter of identifying key user insights. First of all, the majority of us are fanatics. Why else would anyone go out and run all those brutally monotonous miles? Runners are also obsessive (no surprise) about keeping track of personal progress. All those endless miles, all those hills, all those repeats become a body of work. They become a story of individual growth, an epic on a personal level. They are the equivalent of the most timeless of stories: the quest.
