Triathlon de Lausanne Training Plan & Preparation

Course & Elevation

The swim covers 1.5 kilometres in Lake Geneva off the Ouchy waterfront, home of this city triathlon for more than three decades. Straight out of transition the course's defining feature begins: Lausanne rises away from its lake, and the bike course takes that rise on each of its four laps.

The 40 bike kilometres are four identical laps of a good 10 kilometres, and every one contains two ascents to the same high point above the Avenue de l'Élysée: one of roughly 800 metres averaging 5.6 percent with ramps close to 9 percent, and one of about a kilometre at 4.6 percent. Eight times over, those climbs come to close to 585 metres — by far the largest share of the day's total.

The closing run inverts the picture. Its three laps of 3.45 kilometres stay on the lakeside promenade and accumulate around 70 metres over ten kilometres; the profile classifies as flat. For an Olympic distance that makes for an unusually clean division of labour: a climbing and handling contest on the bike, a fast loop with a view of the Alps on foot.

Pacing Strategy

Because the elevation sits almost entirely on the bike, that is where the race is decided. The course sets you the same exam eight times: a short, spiteful climb of around 45 metres, then a descent and a flat stretch. Ride the first ramp only as hard as you intend to ride the eighth — controlled above your base race intensity, never into the red. The descents are not a gift but working time: ride them technically clean and you recover while staying fast.

The classic trap is the first bike lap after the swim: full reserves, race adrenaline and a climb after just 500 metres invite you to sprint every ramp. The bill comes on the last two laps — and then on the run.

Because the flat 10K forgives nothing: there is no gradient behind which a tired leg may quietly slow down, and no descent to hand lost seconds back. What decides the race is therefore how much substance you carry into the run, and whether you can hold its three laps even.

12-Week Preparation

For the Olympic distance on this profile, total effort sits around 2:15 to 3:30 hours depending on your level — short enough to be intense, and on the bike rolling enough that it is never even there.

The demand splits into two very different halves. On the bike, eight climbs of two to three minutes force power spikes above threshold with incomplete recovery between them; the run, by contrast, is a steady, near-threshold sustained effort without terrain changes. It is precisely the tolerance for load changes on the bike — not raw threshold power — that separates the placings here.

Decisive are the series of eight short bike climbs and the state of your legs over the first run kilometres afterwards. Train specifically for that: two-to-three-minute hill intervals on the bike near race intensity with short recoveries, over-under sessions for the constant shifting around threshold, and brick runs that go straight from the bike into a flat, brisk race pace.

Add confident descending and cornering technique, worth real time in a city race, and open-water sessions with sighting practice — the opening swim in Lake Geneva rewards those who swim straight.
