THE RACE FORMAT

ONE ENGINE. FOUR DISCIPLINES.

ERGRUN is a simple, measurable test of endurance capacity. No technical movements. No strength stations. Just your ability to produce output, sustain it and keep moving.

THE PRINCIPLES

01

PURE CAPACITY

Every discipline in ERGRUN tests the same system — your aerobic engine. There are no technical barriers. If you can run and operate a Concept2 machine, you can race ERGRUN.

02

MEASURABLE OUTPUT

Concept2 machines produce objective data. Every metre, every split, every watt is recorded. ERGRUN results are precise and comparable across events and athletes.

03

MULTI-DISCIPLINE

Combining four disciplines reveals where an athlete is strong and where they lose time. A great runner who struggles on the erg is exposed. A great rower who can't run is exposed.

04

LIVE RACING

During erg sections, athletes and spectators see the race unfold in real time. Position changes happen with every stroke. The race is visible to everyone.

THE RACE FORMAT

ERGRUN is structured in stages. Each stage combines running with one erg discipline, repeated for multiple rounds. Stages are separated by a fixed rest period.

STAGE 01

3 ROUNDS FOR TIME

1000M RUN

1000M SKI

REST 10:00

STAGE 02

3 ROUNDS FOR TIME

1000M RUN

1000M ROW

REST 10:00

STAGE 03

3 ROUNDS FOR TIME

1000M RUN

2000M BIKE

Different events and ERGRUN tests may use different combinations and distances. The principle remains the same: RUN. SKI. ROW. RIDE.

SCORING AND RESULTS

Each stage is scored independently. Athletes receive a time for each stage and an overall combined time.

Stage rankings allow athletes to see where they gained or lost time relative to the field. An athlete who wins overall but loses Stage 1 knows exactly where to improve.

Eventually, ERGRUN profiles will track an athlete's performance history across events, showing improvement over time and ranking within their age group and the overall field.

WHO IS ERGRUN FOR?

ENDURANCE ATHLETES

Runners, cyclists, rowers and triathletes looking for a lower-impact way to develop power, threshold and capacity. ERGRUN adds variety and measurability to endurance training.

FUNCTIONAL FITNESS ATHLETES

HYROX and CrossFit athletes who want to develop and test the raw aerobic engine underneath their sport. ERGRUN removes the technical elements and isolates capacity.

CONCEPT2 ATHLETES

Rowers, skiers and cyclists who already train on Concept2 machines and want to compete in a multi-discipline format that rewards their existing skills.
