HOW GTGF EVENTS WORKS

Find. Connect. Train.

01Find a start line

Filter by sport, location or distance and choose an event that matches your goal.

02Show that you are going

Join within GTGF, see who chose the same start line and automatically form an event squad in the Club.

03Connect with the Club

Only say you are going if you want to, and discover who is training for the same start line.

From start line to plan

A race becomes valuable when there is a route towards it.

Choose your event, build the training block and use the community to make the road to the start line less anonymous.
