New York Source to City

New York Source to City starts in New York, New York, on October 17, 2026, organized by Rat Race. It is an expedition-style multisport event rather than a conventional race, built around a rowing and paddling core, with listed stages of 21 miles (34 km), 260 miles (418 km) and 35 miles (56 km) that add up to a far longer commitment than any single-day endurance event.

Preparation for something on this scale looks nothing like a marathon build. The limiting factors are time on the water, upper-body and core durability, and the logistics of eating and sleeping across consecutive long days, not your 10K speed. Runners drawn to it usually come from an ultra background and bring the same habits: high aerobic volume, back-to-back long training days, and gear tested in bad conditions rather than good ones. Blister and chafing management deserves as much attention as fitness.
