All my mileage is outside ether on the bike trails or open road, I do not count spinning or warm up miles of a stationary bike I use before I race... I race HPV Streamliners and ride a Go-1 Velomobile , Bacchetta high racer and Catrike 700 for reck and training. I started riding recumbents 20 years ago after to many injuries forced me of my beloved fixed gear track bike that I rode many a mile on. Personal records on my streamliner is 100 miles in 3 hours 20 minutes and 49 mph at the World's 200 meter flying start. Both of these are a world record for 70 and up riders. I compete in about 20 races a year and have posted a 10 mile TT road course average speed of 30 MPH. Richard Myers Ohio
