No but two of my daughters did 50 miles in training for Ragbrai(sp). They intended to do 75 but couldn't due to the wind.
75 miles?! HFS.
Then again, I did 83.75... over those 3 days! LOL
My left foot and “seat” keep me from doing 40 anymore. I can’t imagine doing a day of RAGBRAI, much less the whole thing.
