I'm considering running the Dizzy Fifties 50k (or 40 or 50 miler) in Huntsville, AL on November 22nd. http://www.dizzyfifties.com/ I'm already registered for some lame rinky dink marathon in Nashville on November 23rd http://www.harpethhillsmarathon.com/PWPmaps/Elevation.JPG Can I substitute the 50 for my last long run - and should I taper for 12 hours or 18 hours before the marathon? Will a heart rate monitor help?
