Ecology and Sustainability

Since 2019, TriO Eventi has been committed to making its events eco-sustainable. We ask for your cooperation in minimising the environmental impact of the event.

  • It is strictly forbidden to litter (gel wrappers, bar packaging, etc.) outside designated areas. Any athlete caught littering by race officials or staff will be disqualified.

  • No aid stations will be provided during the bike leg. Athletes are invited to refill their bottles independently, including at the water station in the race village.

  • During the run leg and at the finish refreshment, there will be no plastic bottles. Paper cups will be used and can be filled at water stations (“Mayor’s water”).

  • At the finish area, only compostable products will be used: cellulose trays and packaging, Mater-Bi cutlery, and paper cups. Toilet paper and napkins are made from unbleached bamboo.

  • From this year onward, all trophies are made of wood.

  • Separate waste collection will be available throughout the race village. Please help us respect it.

  • Event T-shirts are not individually packaged to avoid unnecessary plastic waste.

General Rules

  • The FITRI Technical Regulations apply

  • Compliance with the Highway Code is mandatory

  • The bike course will be on closed roads, supervised by volunteers

Privacy & Images

By registering, participants authorise the use of their personal data and images for informational and promotional purposes, as stated in the Privacy Policy and release form.

Jury and Protests

The Jury is appointed by FITRI.
Any protests must be submitted in accordance with the procedures and time limits set out in the regulations and must be accompanied by the required deposit.
