3 Marathons in 3 Days (3M3D) 2026

Kuranda and the Tropical Rainforest give this race its character: humid, green, and heavier underfoot than a road runner might expect. 3 Marathons in 3 Days is in its 14th year, presenting a distinct Cairns-area challenge for runners seeking more than just finish lines, but a demanding few days. The focus is trail challenge first, comfort second: rainforest terrain, repeat-day legs, and a field that leans adventurous. Expect the Grand Slam Day 1 start line to be active, with early starters and run/walkers settling into the same serious work. The one small mercy is practical rather than soft: cold-weather gear is not needed.
