It starts and finishes on Piazza Grande in Locarno and loops out over the Ascona waterfront in between. Flat, though, it is not quite.

Course & Elevation

The 09:10 start falls on Piazza Grande in Locarno at around 207 metres. The course heads south along the shore and reaches the Ascona waterfront after roughly five kilometres. At the western end of the village the only real climb of the day is waiting: from kilometre 6.1 the road gains just under thirty metres in three hundred and fifty, with ramp sections near twenty percent, lifting you from lake level to a good 222 metres.

After that the loop is flat throughout. It crosses the plain of the Maggia delta by the airfield, turns north again through Solduno, cuts through Locarno and follows the shore road out to Muralto and Minusio at kilometre sixteen before a final loop brings it back to Piazza Grande. The profile stays between 191 and 219 metres overall, close to half the distance is level, and the rest of the climbing is spread over short swells of a few metres each.

The race runs through the sunniest region of Switzerland, in full October autumn light, past palms, lake promenades and the old town of Locarno. Piazza Grande serves as start area, finish and festival ground at once. The race awards the absolute Ticino cantonal title, carries prize money and hosted the Swiss half marathon championship in 2025, which regularly brings a fast field to the line.

Pacing Strategy

This course is fast, and that is precisely where its difficulty lies: there is no terrain to slow you down if you start too ambitiously. The first five kilometres along the shore to Ascona are level and, in a dense field, very easy to run too quickly. Set the pace there that you intend to hold to kilometre twenty, and no more.

The ramp at the western end of Ascona at kilometre 6.1 is short enough to absorb within your effort but steep enough to punish a pace that is too high. Take it with a shortened stride and a high cadence and use the drop back to the shore to find your rhythm again rather than trying to win time back.

The race is decided on the flat between kilometres ten and sixteen, across the Maggia plain, through Solduno and along the shore towards Muralto. There is no change of rhythm there and little shade, but there are open stretches by the water where shelter is worth more than any surge. A half marathon starting at 09:10 in Ticino can turn warm even in October: drink to plan from the first aid station rather than waiting for thirst.

Training plan for Ascona-Locarno Run: 12-week build

For a committed age-group runner this race lasts roughly ninety minutes to two hours. The demand is one long, even effort near threshold: 189 metres of climbing across 21 kilometres means almost the entire race is run inside a narrow intensity window, with no gradient to force a recovery.

The emphasis therefore belongs on threshold work in long blocks: twenty to forty minutes at target half marathon pace, plus long runs with a brisk final third. On a certified, fast course with an ambitious field, what counts above all is the ability to hold a chosen pace exactly across the full distance.

One short, course-specific addition is the Ascona rise. Repetitions of one to two minutes on a ten to twenty percent gradient, each continued straight into a flat section at race pace, rehearse exactly the moment when you have to get back on race pace after thirty metres of climbing.

Preparing for the conditions is decisive. Ascona and Locarno sit in the sunniest region of Switzerland, and an October morning on Lago Maggiore can be considerably warmer than a training block built north of the Alps is tuned for. Rehearse your drinking strategy in warm sessions, test lightweight race kit, and run through the long morning of a 09:10 start, breakfast timing included, at least once.

Climb categories follow the road-cycling convention and rate the terrain itself (length and gradient) regardless of sport: Cat. 4 marks the easiest rated climbs, Cat. 1 the hardest, and HC (hors catégorie, “beyond categorization”) is reserved for the most brutal ascents. Short climbs below the Cat. 4 threshold stay unrated.
