THE DREAM
This is an off-road 50K starting at Guilford Lakes School.
The course passes through several interconnected forest preserves in southern Connecticut.
The entire route consists of rolling forest roads or extremely rocky singletrack, testing both physical fitness and mental toughness.
Picture the course in advance
and find the pace that fits you.
Streets lined with cheers, runners all around.
You'll be part of that scene.
Take it slow with the finish still in you,
and meet the city all over again.
From the joy of finishing to the tough moments — read what runners wrote themselves.
“Before I knew it I was hitting the road crossing and was back at the school and crossing the finish line.”jimmy76mac got lost several times on the leaf-covered technical course and made up for a gel shortage with cola and food to complete the Bimblers Bluff 50K.
“I think this was the lowest point in the race for me.”This runner alternated walking and running over steep climbs and leaf-covered rocky trails at the Bimblers Bluff 50km. Dehydration and inadequate fueling made the later miles tough, but the runner kept going and crossed finish in 8 hours, 16 minutes.
