Congratulations to all the 100 Milers, I've only started back cycling in July 2015, but I'm determined to do a very slow 100 miler in 2016. I ride two or three slow 30-40 milers every week and did plenty of 100 milers when I was a young man, but I'm now 52. My uncle, Alan Boden, was a 100 mile specialist, 3rd in the 1968 National 100 and regular Milk race rider back in the old days, so I'm just hoping it's in the DNA.
Update: May 2016, I'm riding three to four 60 to 70mile rides per week, I've even done a 85 mile ride, so I'm hopeful that I'll cycle 100 miles in 2016.
