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.
