3rd Trigono Trail Run & Mountain Bike

The Mantenia Trail Run, part of the Trigono Trail Race series organized by the Orestiada Hikers Club and Penteliko Forest Walkers & Nature Lovers Society "Drymos," invites runners to explore the breathtaking forest landscape around Mount Penteli on October 31, 2026. This night-time trail run offers participants a unique experience through rugged terrain and dense forests.
The Mantenia Trail is a challenging course covering 30 kilometers with an elevation gain of +1021 meters. The race begins at the Drymos Shelter in Penteli Municipality and follows a route that includes sections along the Bara-Mantenia-Gialia-Pyramid 393 (Greek-Bulgarian border) trail before returning to the starting point.
Participants will encounter varied terrain, from winding forest paths to steep ascents. The race is illuminated by headlamps as runners navigate through the darkness under a canopy of trees. Along the way, there are three hydration stations providing essential water and energy snacks for competitors.
To ensure safety and sustainability, all participants must carry their own reusable bottles or cups for drinking at water points, avoiding single-use plastic waste. Reflective gear is also required to enhance visibility in low-light conditions. The race organizers emphasize environmental responsibility throughout the event, encouraging runners to respect nature by leaving no trace behind.
The Mantenia Trail Run caters exclusively to those aged 18 and over who can register online at trigonotrailrun.webnode.gr/. Entry costs €25 per person, payable via credit or debit card. Registration closes on October 17, 2025, with a maximum of 150 participants allowed.
Competitors will receive race day packages including medals and commemorative gifts upon completion. The top three finishers in both the men's and women’s categories will be awarded trophies, while all who complete the course within five hours are eligible for metal tokens as well.
Health checks and medical support from the Red Cross ensure safety during the event. Runners should take responsibility for their own health by undergoing a pre-race physical examination if needed. All participants must sign liability waivers acknowledging that they participate at their own risk, releasing organizers of any claims arising from unforeseen injuries or accidents.
The race day atmosphere is enhanced with post-event festivities where runners can enjoy free food and mingle in the traditional celebration organized for all competitors who have completed the challenging course successfully.
