DEKA series

About DEKA

DEKA is the sport of functional fitness: accessible, measurable, and designed to celebrate every level of ability.

With three unique formats: DEKA FIT, DEKA STRONG and DEKA MILE. This is your chance to earn your mark, test your fitness, and join a global movement.

DEKA FIT

DEKA FIT is the full arena experience, hosted for the first time in the UK in 2025. It features ten functional fitness zones, each preceded by 500m of running: for a total of 5km.

Some of the zones include:

500m Ski Erg
25 Cal Air Bike
20 Weighted Lunges
100m Tank Push/Pull
RAM Burpees

It’s fast, challenging, and inclusive: a benchmark event that lets you set your standard, break barriers, and show up for yourself in a way that counts.
