Generali Run The Sun Ascona-Locarno Marathon: Course, Route Profile & Map

Course & Elevation

From the start on the Piazza Grande the route first climbs briefly out of the town, the only rise worth naming on the whole course: just under four hundred metres at an average of 3.7 per cent for about fourteen metres of gain, immediately after kilometre zero. After that the course follows the plain east through Muralto, Minusio, Tenero and Gordola into the Magadino flats, turns there and comes back along the same valley floor to Locarno. From kilometre 26 the second part runs south over the Maggia delta into Ascona, out to the western end of the lakefront and back to the Piazza Grande.

That gives the course two very different halves that both feel flat and yet run differently. The eastern one is open plain with long straights between lake and mountains; the western one is town and lakeshore with far more changes of direction. In numbers the route stays between 190 and 228 metres above sea level, roughly three quarters of it sits inside the flat gradient band, and the 175 metres of climbing over the full distance are ripples rather than a profile.

The setting is Italian-speaking Switzerland in early March, when it is still winter north of the Alps. Locarno sits at a good 200 metres on Lago Maggiore, and the organiser sells the event on exactly that: the first marathon of the Swiss year, mild climate, Mediterranean surroundings. This is the first edition, staged by the Associazione Maratona Ascona-Locarno over three days with an expo at the PalExpo and an event village on the Piazza Grande. The marathon is the only race on the Sunday, the cut-off is six hours, and prizes go to the first three overall and to the first three athletes from Ticino.

Pacing Strategy

On a course without climbs, pacing is a question of discipline rather than of reading the terrain. The one place where the route itself intervenes is in the first four minutes: the short rise out of Locarno arrives before you are in rhythm, and it costs double on a flat course, because nothing afterwards will invite you to slow down again. Run it deliberately conservatively and pick up your target pace only on the plain.

The race is decided in the long eastern section between kilometre 8 and 24. Open plain, long straights and few spectators mean little distraction and no change of rhythm; go too fast here and you will only notice on the way back to Locarno. The second part towards Ascona from kilometre 26 has more corners and more spectators, which makes the pace feel easier even though the legs are already marked.

The trap is the sun, not the gradient. The marathon starts at nine on the Lago Maggiore plain, in a region that is markedly milder in March than the rest of Switzerland and that the organiser itself advertises with long hours of sunshine. After a winter of training north of the Alps that is an unfamiliar load. Expect warmer conditions than in training, use the aid stations every five kilometres consistently from the start, and choose your kit for the temperature at eleven rather than the one at nine.

Training plan for Generali Run The Sun Ascona-Locarno Marathon: 12-week build

For an ambitious age-group runner the marathon takes roughly 3:00 to 4:45; the cut-off is six hours. The demand is an even aerobic effort with no peaks: because the course has neither long climbs nor descents, there is no alternation between load and recovery, just the same muscular work at the same pace for three to four hours.

What decides the day is therefore not a section but carbohydrate supply and muscular fatigue from kilometre 30, that is, on the way back from Ascona. Prepare for it with long runs of 30 to 35 kilometres whose closing ten to fifteen kilometres are run at marathon pace, and rehearse your fuelling in training exactly as you intend to take it every five kilometres on the day.

The second emphasis is robustness on flat asphalt. A course with three quarters of its distance inside the flat band means a very high number of near-identical strides; the usual consequence is not breathlessness but muscular fatigue in calves and quads. So put at least the long runs and part of the tempo work on the road, and add strength work for calves, glutes and trunk.

Among the conditions, season and climate count. A marathon in early March means building through December and January, often in cold, wet weather or on a treadmill, and then racing in the warmest and sunniest corner of Switzerland. Plan at least two of the long runs for the second half of the day and in mild weather, test race and drinking kit under those conditions, and if you can, travel a day early to collect your bib at the PalExpo expo, because it is not issued on race day.
