It's been a dream of my father-in-law's to run the Mont Blanc Tour. His friends (who are awesome) operate a running guide company out of Minnesota, so when they put the UTMB on their roaster, we were in.
Adventure Running Co organized the trail itinerary, lodging and food, we just RAN. Or power walked A LOT because it was about 33,000ft of climbing and then about the same in descent. My husband and father-in-law are ultrarunners, so the 100-mile distance over a couple of days, wasn't too worrisome for them. I, however, was quaking in my trainers.
