Running and cycling have become connected sports. When runners and cyclists join a race, they want status, results, and social network integration -- before the race, after the race, and even while on the move. Because each athlete has a different mobile device, how can a single technology support an entire race, from registration to results?

Enter Athletepath, a Portland Incubator Experiment startup. When Athletepath faced this challenge, they chose responsive web design (RWD) instead of creating native apps for every conceivable platform. Combining RWD and SMS for messaging provides technology that serves the largest number of users with the best cost-to-benefit ratio possible.

At this month's Mobile Portland, front-end developer Christian Reed will explain how and why Athletepath built its platform.
