I'll be going through the whole "starting over" game in about 4 - 5 weeks.
If anyone followed my "What it takes to be Super" blog series over in the Clyde forum, you're familiar with the pain I was experiencing on the 300 and 400k rides, and that after the 400k it put an end to my series. Well, it turns out that it's not related to saddle position or choice of shorts as I thought (directly), but those things may have been contributory. Mostly, riding for 18 - 25 hours at a time on a chronic fissure was what caused my pain and problems; and my surgeon said it's more than likely that I'd had this problem for 6 months of longer! How I managed to not know, I'll never know. He was astonished that I rode more than around the block. But I've been off my bike for the past month because of it, and I go in for surgery on Friday. After that it's a 4 - 5 week recovery period before I can start riding again.

2010 S-R attempt; down the tubes... Although just riding the 300 and 400 was some memorable time.
2nd go at an R-12; once more foiled at 5 months... 3rd time's a charm, right?
Between sudden inactivity and corticosteroids, in just a month I put on a lot of the weight I had lost (even though I've damned near quit eating). It's going to be a rough road back if I want to ride the spring series with SIR next year.

Reading people's comeback stories give me hope that it's going to go well. So many people have come back from far worse; I can do this.
