Triathlon International du Lac d'Annecy: Course, Elevation & Route Profile

The Olympic distance at the Triathlon International du Lac d'Annecy turns on something few other races ask of you: the bike split is stopped back in Sévrier, and the last kilometres to the transition area are ridden without a clock. Between 1.5 km in the lake, the Col de Leschaux and two flat laps on the promenade, the day is decided by how you handle the joins.

Course & Elevation

The day starts and ends on the same lawn. Le Pâquier, the big lakeside park in the middle of Annecy, holds the swim start, both transition areas and the finish. Out of the open water you run straight into T1, then head down the west shore to Sévrier and inland over the Col de Leschaux, before coming back to that same lawn for two laps on foot along the water. You see one lake from three angles in a single morning: from the water, from the pass road, from the promenade.

The sequence carries a quirk that shapes the whole race. The bike leg is scored only as far as the car park in Sévrier; the remaining kilometres back to the second transition on the cycle path are ridden but not timed. On top of that the day is broken up by control points: the end of T1, the top of the pass, T2 and the finish each carry a cut-off, and missing one ends your race. This is not a course you repair in the closing stages.

The event is run by a local club and an entirely volunteer team, with a field of around 1,200 across a weekend: youth races and the adapted-sport event on the Saturday, the Olympic distance on the Sunday. The mountains stand around the Lac d'Annecy, and apart from the pass road almost nothing on the course leaves sight of the water.

Pacing Strategy

Effort here is unevenly distributed, and it loads early. After 1.5 km in the lake you get less than twenty minutes of flat shoreline before the long climb starts. Come out of the water hunting a group and you are already deep in the red by the time the road tilts up. Those first kilometres on the bike are the best chance you get all day to settle your breathing and heart rate.

The race is decided between the top of the pass and the start of the run. The untimed closing section on the cycle path is where you can still change your day: it costs you nothing on the clock, so it belongs to drinking, loosening the legs and an easy cadence, not to a duel with the rider ahead.

After that the run laps forgive nothing. Across two flat five-kilometre loops there is no gradient to brake an over-ambitious pace for you, and the promenade lies open to sun and wind. The classic trap is therefore not the climb but the first kilometre out of T2, which feels easy because you have just spent several kilometres freewheeling.

Training plan for Triathlon International du Lac d'Annecy: 12-week build

Plan for roughly two and a half to three and a half hours over this Olympic distance. The demand is not that of a flat short-course race: one long climb lifts the intensity for about half an hour on the bike, and what follows is a purely aerobic, evenly paced run with nothing external to set the rhythm. You are preparing two quite different demands inside one race.

The key passage is the handover from swimming into the climb. That is exactly what brick sessions are for here: start in open water and move into a long, hard ascent a few minutes later. Since both transition areas sit on the same lawn, it also pays to rehearse T1 in a wetsuit under time pressure, because a cut-off falls between leaving the water and getting on the bike, and it can end your day.

The conditions come off the lake. Alpine lake water stays cold even at the end of summer, wetsuits are allowed only up to a set water temperature, and if the water is too cold the swim is dropped altogether. If your open-water experience comes from a pool, practise the cold start repeatedly. Wind builds over the open water as the day goes on, the run promenade offers neither shade nor shelter, and the air at the top of the pass is noticeably cooler than down at the shore.

That gives three priorities: open water with mass starts and a cold first contact, longer threshold blocks uphill straight after a hard swim, and flat tempo running on tired legs where you have to set the pace yourself. The rest is organisation, and on this course it is worth more than it is elsewhere.
