Asics SaintéLyon: Course, Elevation & Route Profile

Course & Elevation

The race starts at 09:00 at the Halle Tony Garnier in Lyon and finishes there too. The outward leg runs the diagonal in reverse over the Monts du Lyonnais to Saint-Étienne and has to be completed inside thirteen hours; it is not ranked, and everyone paces it as they choose. A meal and a dedicated rest area wait in Saint-Étienne, and then it is back over the classic course - with a front-row start and the yellow bibs that identify the ultra runners for the whole return.

Measured as a loop the course comes to 155.9 kilometres and 4,351 metres of climbing, distributed almost symmetrically: 27.8 per cent up, 27.6 per cent down, only 18.3 per cent flat. The hardest single climbs sit on the outward leg between kilometres 35 and 55 - one of them averaging sixteen per cent - and on the return from kilometre 114, where the 175-metre, thirteen-per-cent climb arrives that the 80 km course knows at its own kilometre 37.

The field is capped at 800, the smallest of the weekend. The format has been officially on the programme since 2019 after years of being run unofficially; Alexandre Boucheix won its first three editions in the men's race. The barriers apply in both directions: Saint-Étienne has to be reached by 22:30, Lyon by 16:00 the following day.

Pacing Strategy

No other race of this length puts the central tactical question so explicitly: how much do you invest in something that is not scored? The outward leg allows thirteen hours for 76 kilometres and around two thousand metres of climbing. That is comfortable - and the temptation to get it done quickly in order to buy more rest costs more on the return than the hour gained is worth.

The break in Saint-Étienne is the real lever. It is the only moment of the race where you can change clothes, eat and actually lie down, and the only one where the body has to switch from a daytime rhythm to a night already spent awake. Break too briefly and you set off on the return chilled and underfuelled; break too long and you never properly wake up again. Plan it as a fixed length beforehand and hold to it.

The race is decided in the second half of the return, from about kilometre 114. That is where the classic course's steep climbs sit, where the night is longest, and where you have already been going for more than twenty hours. Run the outward leg genuinely conservatively and this is where you move up - for the whole return you wear the yellow bib and run through the field of the 80 km starters, which is the biggest psychological advantage this format offers.

Training plan for Asics SaintéLyon: 12-week build

156 kilometres with 4,350 metres of climbing and a break in the middle take age-group athletes somewhere between twenty and thirty-one hours - the barriers allow thirteen hours for the outward leg and a sixteen-and-a-half-hour window for the ranked return. The demand is a very long aerobic one with a high eccentric component and, unlike any normal ultra, a forced interruption.

That interruption is trainable and almost never trained. Two sessions in one day with several hours between them - long in the morning, long again in the evening and in the dark - simulate exactly what happens in Saint-Étienne: restarting cold, stiff legs, running on after eating, warming up in a state where warming up is unpleasant.

The running-specific emphasis is the same as on the 80 km course, only more so: downhill running under fatigue, spread across more than four thousand metres of descent, plus base sessions of six hours and up and back-to-back weekends. Run the outward leg technically downhill and save the legs there, and you win the return.

Conditions are a double stimulus: the outward leg runs in November daylight at single-digit temperatures, the return at night at up to 870 metres, where snow and ice occur regularly. Kit has to cover both, and the drop bag in Saint-Étienne is the only chance to make use of that. Pack it as though it were the most important piece of equipment in the race - because it is.
