MapMyFitness is a veteran of the online health and fitness space, with the first iteration of its website appearing back in the summer of 2005. Since then, the startup has developed a suite of fitness-oriented websites (like MapMyRUN.com, MapMyRIDE.com, MapMyWALK.com, et al) to let users track and store their running, cycling, walking and hiking endeavors, along with accessing a database of international routes, fitness calculators, events listings and more. MapMyFitness has long had a solid community of committed users, but it's seen a significant bump in adoption of late, this week passing 9 million registered users.Building on this uptick in adoption, MapMyFitness is today launching one of the most significant updates to its platform since its rebranding back in 2007. The startup has completely rebuilt its portfolio of websites, adding a number of new features, with the main attraction being a new service called "Courses," which includes "one of the most advanced integrations of Google Maps’ API to date," says CEO Richard Jalichandra. read more..
