The Annecy basin brings together everything needed for an ideal trail running area. The immediate proximity between Lake Annecy and the mountain ranges offers exceptional variety: technical high-altitude paths, forest singletracks, steep climbs and committed descents.
This landscape makes it possible to pack in up to 2,000 metres of positive elevation gain in a single outing, while starting from lakeside level at 450 metres above sea level. The Bornes and Aravis massifs make for brilliant year-round training ground.
The variety of trails around Annecy means you can mix things up: from short, fast trail runs to mountain ultra-distance formats.
Mont Veyrier is the signature trail running route in Annecy. Starting from Petit Port or Col des Contrebandiers, this 1,291-metre summit offers around 850 metres of positive elevation gain. The path alternates between rocky technical sections and woodland stretches, with superb panoramic views at the top.
Trail runners especially enjoy the Mont Veyrier - Mont Baron loop, which extends the effort along an airy ridge. Allow 1 hour 30 minutes to 2 hours 30 minutes depending on your level and the intensity you are after. This route is excellent preparation for mid-mountain races.
At 2,351 metres, La Tournette is the iconic peak of the Bornes massif. Several routes let you reach it by trail, including from Chalet de l’Aulp or Montmin. Elevation gain quickly reaches 1,400 to 1,600 metres depending on your starting point.
This demanding route calls for good fitness and trail running experience in the mountains. The rocky sections near the summit require care and technique, especially on the way down. Save this outing for stable, fine-weather days.
For a less vertical but just as demanding endurance outing, the route around Lake Annecy offers around 40 kilometres of varied trails. By favouring forest paths and singletracks rather than the cycle path, you create a rolling trail route with constant views over the lake.
This loop lets you include technical sections such as the trails in the Semnoz forest or the balcony paths on the Talloires side. Ideal for building aerobic endurance in trail running.
Routes around Annecy are known for sustained elevation gain. Keep an even pace on the climbs, and do not hesitate to hike the steeper sections to protect your heart rate. The aim is to keep the effort steady rather than burn through all your energy in the first few hundred metres.
Use your trail poles on long climbs: they take the load off your thighs and improve propulsion. Around Annecy, some climbs average more than 30% gradient.
Downhills in the Annecy mountains often include rocky sections, roots and steep stretches. Work on your descending technique: look far ahead, keep your footwork light and dynamic, and lean your torso slightly back on steeper slopes.
Invest in trail shoes with good cushioning and a grippy sole such as Vibram. Protection against repeated impact helps preserve your joints over the long term.
The weather changes quickly at altitude around Annecy. Always carry a waterproof windproof jacket, even when it is fine in the valley. Also plan for water and food: mountain outings use up plenty of energy.
In winter, some paths become impractical or unsafe. In that case, opt for snowshoe hikes in Annecy to keep enjoying the mountains safely.
Trail running in the mountains calls on specific physical qualities: aerobic endurance, lower-body strength, proprioception and running technique. Mix long easy runs, short and intense hill sessions, and strength training.
Build elevation gain into your plan gradually. If you are just starting out, begin with routes offering 300 to 400 metres of D+ before aiming for the big summits. Consistency matters more than intensity if you want lasting progress.
Joining outings led by mountain professionals helps speed up your technical progress and discover new routes safely. Specialist guides will pass on the right habits for navigation, effort management and mountain safety.

Beyond suitable trail shoes, a few pieces of kit make things easier on the Annecy trails. A 5 to 10-litre trail pack lets you carry the essentials: water, food, a jacket, a first-aid kit and a charged phone.
Trail poles are especially useful on steep routes such as La Tournette or Semnoz. They improve balance, take pressure off the knees on descents and boost propulsion on the climbs.
For long outings or specific training sessions, a GPS watch with a barometric altimeter helps you manage your pace and track your progress on elevation gain. This objective data makes training planning much easier.
