About this event in the Jura in Saint-Laurent-en-Grandvaux
Les Segments du Grandvaux : get your trainers on!
To mark the opening of the Espace Trail du Grandvaux, the Communauté de communes la Grandvallière is launching Les Segments du Grandvaux, a sporting challenge open to everyone, from beginners to experienced runners.
How does it work? Over 8 weeks, participants are invited to test themselves on 4 running segments across the area. Using the Strava app, everyone can try to improve their time, challenge themselves and track their ranking.
A challenge centred on sport, exploring the local area and, above all, the pleasure of running!
Les Segments du Grandvaux takes place on 4 different segments, with 2 weeks devoted to each segment.
During this period, each participant can complete the segment as many times as they wish to improve their time and ranking.
For each segment, performances are recorded on Strava and used to establish a ranking.
But here, you do not need to be the fastest to be in with a chance! The overall ranking takes both performance and consistency into account. The aim is therefore to take part regularly throughout the challenge and try to improve as the weeks go by.

Good to know : you do not need a paid Strava subscription to take part. A free Strava account is enough.
How do the rankings work?
Each segment has its own ranking based on performances recorded during its designated two weeks.
An overall ranking will also be compiled at the end of the four segments.
This will recognise two elements
speed, to reward the best performances; consistency, to recognise participants who take part in the challenge throughout the 8 weeks.
The overall ranking will therefore reward both sporting performance and commitment to the challenge.
Because a small sporting challenge is always more motivating with a reward at stake, several prizes will be awarded to the highest-ranked participants.
The prizes will recognise, in particular
the best performances on the different segments; consistency throughout the challenge.
The prizes will be provided in partnership with local organisations and businesses, also offering a chance to discover the area's skills and services.
Above all, Les Segments du Grandvaux is an opportunity to put on your trainers and discover or rediscover the area's paths.
The Espace Trail du Grandvaux offers a total of 11 routes, suitable for different levels and available on Jura Outdoor. Les Segments du Grandvaux complements this offering with a fun, evolving format that allows everyone to set their own goals.
