BF and I have been planning on riding the Horsefarm 100 coming up Oct 19th. I just started riding in May and ride very consistently. BF on the other hand has not and will not be able to ride at all this week because of work.

I noticed on a recent 43 mile ride (with no stops) that my lower back was very sore. It did not last more than a day or so but I was pretty uncomfortable while riding.

Last thursday I rode a very strong 33 miles at 19.2mph with no back pain until the next afternoon which may more relate to riding my horse after that bike ride now that I think about it.

So I raised my concerns to BF about being able ride 100 comfortably and he admitted that he was out of shape for it last year too, bonked twice but was only sore/ tired for a few days. He said that he thought I would have no trouble if I rode at 15-16 mph and stretched at the rest stops. However, we are talking about a 7 or so hour ride. This seems daunting to me.

He wants to do 100 so he can say he did it. There are other options. A 55 that stays in town or a 45 that just does the horse farms.

Basically I have no idea what to do and although BF has done the ride twice his motives and thinking confuse me so I would love some advice.
