Back in 2004 before there was Facebook, Google Maps APIs and the iPhone I started a social network called ontri.com - I was really into triathlon and marathon running at the time and there were no sites out there that focused on the middle of the packers like me at that time. The site has been a side project for me, it adds new users every day but could really use someone who is both technical and into endurance sports to take it and run with it (no pun intended). It makes money and I don't spend much time with it so I have no reason to shut it down or give it away but I'm open to creative partnerships as I would love to see someone fulfill its potential. If interested and serious, email jon at ontri.com
