I'm a geek. I'm turning (back?) into a bike geek right now, but I'm a lifelong geek in oh, so many ways. So, perhaps being back in the saddle is just another way for me to indulge my geeky nature?
It's in two parts: a downloadable (and free!) app for your phone, and a website to which, once you've registered (also free), you upload your info. Basically, the GPS unit on your phone tracks your location, distance travelled, speed, (as well as linking to your bluetooth heart rate monitor if you have one) and once the info is uploaded to the website you can see all kinds of cool stuff. Like how slow I am.
I like it. It ticks my boxes. See if it ticks yours.
