Congrats on riding around the world. You should have said something when you came up with the idea so that it would be documented for the misses.
I never set a goal as you did, but since I started riding again, three years ago, I started keeping track of all my mileage between the two bikes. I hardly had any miles the first 5 months as we had a very cold winter for Florida and I didn't ride. But since then, I have racked up nearly 10,000 miles (just over 7,400 on the road bikes and just over 2,300 on the hybrid). If I don't kill myself with these injuries, I may get my trip around the world.
