CT’s Hardest 50k! This Fat Ass is a Graduate Level run, meaning you will be on some of CT’s most technical and gnarly trails: first the Regicides (West Rock’s “Blue” trail) and then The Quinnipiac Trail (another of CT’s famed Blue trails). Hence, the Blue 2 Blue Challenge (h/t Alex McDaniel for the idea). There’s probably a good 6,000 feet of climbing and the majority of it is extremely technical.
