S.C.A.R. Swim Challenge

What this race demands

The S.C.A.R. Swim Challenge demands exceptional multi-day endurance and recovery capacity to complete 66.9 km across four separate reservoir stages over four consecutive days.

Given the multi-day stage format with extended daily swimming durations, athletes should target 60 to 90 grams of carbohydrates per hour during effort to maintain glycogen stores and support recovery between stages.
