324k huh? Damn, that's a no-joke distance for April and over the cobbles. The thought is tempting but I can't see being able to train up to that distance during a Luxembourg winter. I'm already down to mountain bike only rides with the rain and snow we've had. Thanks for posting though, if only I could head to Spain for spring training!
Wait, I just read the date...the Ronde is on MAY 25th this year, not April? Or just this Sportive?
