CT’s Hardest 50k! This race 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. There’s over 6,500 feet of climbing and the majority of it is extremely technical.
