The S.C.A.R. Swim Challenge is a 4-day, 66.9 km stage swim across four reservoirs along the Salt River in Arizona.
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.
Multi-Day Endurance
Completing four distinct stages over four days requires rapid physiological recovery and sustained muscular stamina to manage high cumulative fatigue.
Distance Volume
The total span of 66.9 km demands specialized pacing and stamina to sustain continuous forward propulsion in open water over extended hours.
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.
