DEKA vs MacTuff: distance, stations, price & difficulty compared (2026-27)

DEKA is a functional fitness race series run by Spartan Race and billed as the decathlon of hybrid fitness racing. Every DEKA event uses the same ten DEKA Zones. The time for each zone and the total time are recorded, so athletes can compare results with their own previous marks and with a global leaderboard.

The flagship DEKA FIT puts 500 m of running before each zone, for 5 km in total. DEKA MILE uses 160 m runs for one mile in total, and DEKA STRONG is the ten zones with no running. There are also DEKA Ultra (50 zones and 25 km of running) and DEKA ATLAS, a heavier ten-zone test with a 30-minute cap. Athletes who finish STRONG, MILE and FIT in one calendar year earn the DEKA Trifecta. Heats include Elite, Age Group, Teams and Ruck, so the series suits gym-goers as well as competitive athletes.

MacTuff is a Scottish events company, MacTuff Limited of Glenrothes, Fife, that runs mud and obstacle challenges for adults and children along with a road half marathon. Its obstacle events include the Really Muddy runs at Castle Fraser, Sauchen near Aberdeen, and in Fife and Kinross, plus MacTuff Kids events in Fife.

The Really Muddy events offer a 3 km kids course and 5 km and 10 km adult courses through mud, water and obstacles. MacTuff Kids is a roughly 3 km course where children run alongside participating adults, with obstacles built in two heights so that adults and children can tackle them together; the organiser sets adult-to-child ratios by age. Participants receive a T-shirt and medal, with free parking, spectator access, photos and bag drop. The events are aimed at families, groups, charity fundraisers and newcomers to obstacle running rather than competitive racers.
