Every prediction is checked against real finisher times and placings, 2.4 million results across 1,800+ race editions and more than 300 distinct triathlons dating back to 2002, the kind of field-comparison depth most apps in this category simply do not have. The plan you take to the start line is one the data says you can hold. FOR COACHES CrushThisCourse is built for coaches working with athletes all season, not just on race day.
