GT24h Relay
Running alone… or running together
The GTLC Backyard Relay follows the same format as the solo race, but with a team element.
Here, it’s no longer just a matter of individual endurance.
It’s also a matter of strategy, teamwork, and team management.
A loop.
A departure every hour.
But this time, you share the effort.
The principle
Teams consist of 2 to 4 riders.
Every hour, a team member sets off on the 6.706-kilometer loop.
There’s just one rule: every team member must run at least one lap.
As for the rest, the strategy is up to you.
A team race
In the Relay format, every decision counts:
- who takes the first lap
- who runs at night
- who saves energy for the final hours
Between each departure, the base camp becomes the focal point of all discussions.
A different challenge
The GT24H Relay lets you experience the intensity of a Backyard while sharing the effort.
This is the perfect format for:
- running with friends
- represent a club
- take on a collective challenge
For 24 hours, each loop becomes a piece of the puzzle.
