I’d like to propose a new thing called “Mariana Trenching”, where a rider descends the depth of the Mariana Trench, 36,201 feet.
The rider must descend the full elevation by lapping a single road/trail (no loops).
On each lap, the rider must climb back to the top under his/her own power. Rider will be timed for total elapsed time including all descending and climbing.
