I am a former Marine, marathoner, and Ironman triathlete who lost the ability to run a few years ago because of knee and hip damage (I guess I shouldn't have been surprised). A friend of mine who is an ultramarathoner and mechanical engineer built me a new kind of bicycle that basically lets me run outdoors without impact. Here is a photo of me on it in Arpil at the start of the Rosarito to Ensenada 50 mile ride, my first endurance event since about 2003. We have a website with a video and would love to get feedback from other runners to get a sense of whether there are other people out there who might be interested in using these for cross-training or as a substitute for running. Please go to www.elliptigo.com for the video and to let us know your thoughts through our survey. Really appreciate it and happy running . . .
