Run In Lyon by Harmonie Mutuelle.
Run In Lyon is the biggest running Sunday in France outside Paris: 33,000 entrants were registered in 2025, and all four distances start and finish on the Place Bellecour. The marathon is flat - a good 300 metres of climbing over 42 kilometres - but it runs along both rivers, which makes it a race about evenness rather than strength.
No date has been announced for the next edition yet. The course, elevation and route profile are from the most recent edition.
Run In Lyon: Course, Elevation & Route Profile
The course is one large loop through Lyon that uses both rivers, one upstream and one down. From the start in Vieux Lyon it first runs north along the Saône to the turn at the Pont Paul Bocuse, then back south on the quays below the Croix-Rousse, across the Place des Terreaux and over the Pont Morand to the Rhône bank. There a loop takes in the Cité Internationale and the Parc de la Tête d'Or, the city's big park.
The second half runs the Berges du Rhône south past Part-Dieu, over the Pont Raymond Barre into the Confluence district and on into the Parc de Gerland with its stadium. From there it heads back north to the finish on the Place Bellecour. The profile stays almost entirely between 160 and 175 metres; the only rise worth the name sits between kilometres 16 and 18 around the Cité Internationale, and right at the end, just before Bellecour, the road lifts fifteen metres again. 54 per cent of the course is flat and there is effectively no steep section.
The event is run by A.S.O., the organiser of the Tour de France, and is deliberately built as a festival of four distances - marathon, half marathon, 10 km and an untimed five-kilometre Run Solidaire, in 2026 in aid of AFG Autisme. The half and the 10 km were already sold out for 2026 by early September. The marathon is timed at kilometres 10, 21.1 and 30; the limit is five and a half hours, after which the closing vehicle passes and the roads reopen.
| Start | Length | Ø | Max. | Gain | Cat. |
|---|---|---|---|---|---|
| km 6.4 | 0.5 km | 3.4 % | 6 % | +15 m | — |
| km 16 | 0.6 km | 3.5 % | 4.9 % | +20 m | — |
| km 17.3 | 0.3 km | 3.9 % | 5.7 % | +13 m | — |
| km 42.4 | 0.5 km | 3.1 % | 3.2 % | +15 m | — |
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.
How to pace Run In Lyon.
Start under control
On a course whose entire profile fits inside a twenty-five-metre window, there is no point at which the terrain does the pacing for you. Pace is a decision from beginning to end, and the only external influence is the field: marathon and half start together in waves from the Place Bellecour, and for the first hour you are inevitably running with a great many people who have a different distance ahead of them.
Hold your rhythm
The second peculiarity is the quays. For long stretches the course runs on the riverside promenades of the Saône and the Rhône - long, straight, entirely level sections with no bends and no landmarks. They are fast and treacherous at once: too long and too sluggish a stride costs more over hours here than any gradient would, and a wind following a river valley has nothing to break it on an open promenade.
Spend what is left
The race is decided in the second half on the Rhône bank, between Part-Dieu and Gerland. From kilometre twenty-five nothing structures the race from outside any more; anyone who rode the big shared field too fast early loses time there kilometre by kilometre. The final fifteen-metre rise up to the Place Bellecour is objectively laughable and is still perceived as a climb after forty-two flat kilometres - that is where the reserve belongs.
Training plan for Run In Lyon: 12-week build
Build the base
For age-group runners the Run In Lyon marathon is a three to five-and-a-half hour effort; the limit is 5:30. The demand is a steady aerobic one with no anaerobic component - no climb forces anything and no descent hands anything back. A course like this is the right one for a personal best; anyone who has never run a marathon without terrain to give it rhythm regularly underestimates how demanding that is mentally.
Train race pace
The training emphasis is therefore race-pace endurance on flat ground: long runs with forty to sixty minutes at marathon pace in the final third, and threshold runs of twenty to forty minutes. Hill training buys nothing here; the course's three hundred metres are spread over forty-two kilometres without ever becoming a climb.
Rehearse the course
What does pay is running technique on long, straight sections. Riverside promenades and cycle paths without bends invite a cadence that drifts downwards and only shows up as lost pace after hours. Some of the long runs should therefore deliberately be done on that kind of ground with a controlled cadence - the stimulus is technical, not aerobic.
Arrive fresh
Conditions are those of an early-October Sunday in the Rhône valley: mild, often damp in the morning, and more exposed to wind on the open quays than in the city centre. Since the 2026 start times are not yet published and the marathon has gone off in the early morning in the past, the breakfast and fuelling routine should be rehearsed for an early start. Because all four distances use the same city centre, the field is dense over the opening kilometres - a few training runs in which race pace is not reached until two or three kilometres in are realistic preparation.
