The Sines Triathlon is a 100 km endurance race featuring a 2 km swim in Sines Bay, an 80 km bike segment, and an 18 km run that finishes on the Vasco da Gama Promenade.
What this race demands
The Sines Triathlon demands sustained endurance across three consecutive disciplines totaling 100 km, requiring efficient pacing from the 2 km swim through the 80 km bike and finishing with an 18 km run.
Multidisciplinary Endurance
Athletes must manage significant cumulative fatigue as they transition from a 2 km open-water swim to an 80 km bike leg and finally an 18 km run.
Pacing Discipline
Because the total distance spans 100 km without a break, athletes must maintain a controlled effort to avoid early depletion before the final run segment.
Given the total duration of the race is likely to exceed three hours for most participants, athletes should target an intake of 60 to 90 grams of carbohydrates per hour during the bike and run segments to sustain energy output.
