Experience the CIEL Ferney Trail: something for every nature lover

This isn’t one of those intimidating, all-or-nothing endurance races. The CIEL Ferney Trail is designed so that everyone, seasoned athletes, weekend hikers, kids, and groups of friends, can participate on a level that fits. The four course options offer radically different challenges:

• C-Care 35km: For dedicated trail runners, this route tackles Lion Mountain’s upper slopes before winding through the hills of Ferney. Expect steep climbs, rugged terrain, and sweeping island views. If you’re training seriously, this is your race.
• Bank One 18km & CIEL 10km: Both offer a classic Mauritian mix, open pastures, rolling hills, and lagoon vistas above Grand Port. The 10km course is the most accessible but still throws in some good climbs, while the 18km is a genuine challenge for regular runners.
• Sunlife 5km Fun Run: Geared towards families and anyone looking for a relaxed, active morning. Kids love crossing a shallow river and weaving through Ferney’s famous pastures.

One clear advantage for tourists: none of the routes interfere with the protected Vallée de Ferney forest conservation zone. You’ll get memorable landscapes and glimpses of Mauritian wilderness, but without endangering sensitive plant and animal life. That’s an approach that really matters here; Mauritius takes its conservation seriously.

Inclusivity and local spirit: what makes the event special

The CIEL Ferney Trail isn’t just a race, for many, it’s about solidarity and giving back. Over Rs 1,135,000 was raised for local NGOs this year, including Breast Cancer Care, APEIM, and the Muscular Dystrophy Association. If you contributed during registration, thank you; each group will receive its donation after the prize ceremony onsite.

One unique highlight is the use of joëlettes: single-wheeled hiking chairs that allow people with mobility challenges to join the trail experience. In 2026, two young athletes, Kiara and Alexandre, will participate thanks to these adapted seats and a team of volunteers, including two from RodTrail in Rodrigues. You’re likely to hear the crowd cheering a little louder as they pass by. Having seen this in person at last year’s run, I can tell you: it’s impossible not to feel the infectious energy.

Arrival, logistics, and practical tips

If you plan to spectate or support a participant, here’s what to know. Access has never been easier: Ferney’s upgraded entrance, wider road and new roundabout make arrival much smoother (less honking, less dust). There are pavements and improved drainage too, so even if we get a rare September rain, walking to the start area is safe.

Bib and number collection happens a few days earlier in Floréal, so if you’re coming from further afield, give yourself an extra day for the drive, traffic builds up around Floréal mid-morning, especially on event weeks.

Remember, although September is technically winter here, daytime highs reach the low 20s Celsius with little humidity. You’ll want sunscreen, a light pullover for the early start, and plenty of water. The event area turns festive, with food stalls and local produce stands to explore after your run. It’s a great family day out, not just a sporting challenge.

Looking ahead

With 19 years of building Mauritius’ outdoor sporting culture, the CIEL Ferney Trail continues to attract athletes, nature lovers, and curious travelers looking for a way to connect with the island’s authentic side. Whether you run, walk, or just come for the atmosphere, the heart of Ferney is wide open on September 12. See you on the trail, and maybe at the coconut stand after the finish line.
