Question for you long distance multi-sport types.

I try to do my long runs (currently 10 miles) on Wednesday or Thursday morning, so that I'm fully recovered for my long rides (up to 100 miles) on Saturdays. This seems to work out fairly well for me.

This coming Saturday, I'm doing a 300K (189 mile) ride with an advertised elevation gain of 13000 feet. Failure (ie. not finishing) is not an option, as this is an unsupported ride on middle-of-nowhere roads likely to have little or no cell coverage. It's been several years since I've done this distance in one day (and I'm fairly certain I've never done that much climbing in one day), so this ride will definitely challenge me.

Because of my schedule this week, I can't do my long run on Wednesday, so I'm trying to figure out if doing it on Thursday will allow me enough time to recover by Saturday. I'm strongly leaning towards moving the long run to Tuesday instead, but figured I'd ask for some feedback nonetheless.

Thoughts?
