I got ninja drafted today... I was about 15 miles into my commute home on one of the rural roads I use. I was on the shoulder and looked into my helmet rear view mirror and lo and behold a cyclist is coming up on me. I was going about 15 mph so I figured he wanted to pass me but he got directly behind me. A minute later and he still hadn't passed me. Even though I was tired I picked up the pace to 20 mph for about 2 miles. Then I looked back and he was gone... he must of turned off somewhere. I was used... I was ninja drafted.
