On its long course the Colle San Marco Winter Trail takes you from around 700 to over 1,400 metres in January: mountain paths near Ascoli Piceno, about 1,000 metres of climbing over 20 km, and a single ascent that accounts for half of it. Your preparation belongs to those four kilometres and to the steep way back down.
The race leaves from the Colle district near Ascoli Piceno, and the first kilometre stays almost level. Three short ramps then follow one another and lift you to just under 1,000 metres by km 4.5. The last of them, at around 15 percent on average, is the steepest and the first real test of the morning.
After a small dip, the real race begins at km 5. For four kilometres the path climbs almost without a break, a good 500 metres in one go, until the high point at around 1,440 metres arrives just past km 9. The refreshment station sits at halfway, and from there the loop drops below 900 metres by km 14.
That is where the counter-climb stands, the part most likely to catch you out: a little over a kilometre, around 140 metres of gain, with short and very steep pitches. From km 15.5 the way leads almost entirely downhill to where you started, and finish refreshments are waiting there. The terrain gives you little rhythm anywhere on the loop: more than half the distance is steep, up or down, and only a small remainder is flat.
| Start | Length | Ø | Max. | Gain | Cat. |
|---|---|---|---|---|---|
| km 1 | 0.7 km | 10.2 % | 16.8 % | +67 m | — |
| km 2.2 | 1.2 km | 9.7 % | 14.8 % | +114 m | Cat. 4 |
| km 3.6 | 0.8 km | 15.1 % | 23.9 % | +117 m | Cat. 4 |
| km 5.1 | 4.1 km | 12.3 % | 25.7 % | +502 m | Cat. 2 |
| km 14.1 | 1.4 km | 10.6 % | 28.3 % | +143 m | Cat. 4 |
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.
Split the day into three blocks: the ramps up to km 5, the long ascent, and everything after it. The first block is only a run-up. On fresh legs the three ramps look runnable, and that is the first trap: push the 15 percent pitch and you pay for it on the mountain soon afterwards. Walk the steep metres from the start.
The race is decided between km 5 and km 9. At over twelve percent on average this is walking ground for most amateur runners, so plan a strong, even stride and run only where the path eases. You want enough left at the top to descend cleanly. Make deliberate use of the refreshment station, which comes shortly after the high point.
The second trap is the descent itself. Over 550 metres of downhill invite you to win time back, but heavy braking delivers you to the counter-climb at km 14 with empty quads, and around 300 metres of descent to the finish still lie beyond it.

Expect roughly three to four hours, depending on your climbing fitness and sureness of foot. That time is never even: a long aerobic effort carries the race, with strength-heavy spikes on the steep ramps and a lot of braking work for the muscles on the way down.
Three places need specific preparation. The main ascent asks for 40 to 60 minutes of unbroken climbing at a hiking pace, on legs that have already worked. The descent after it tests your quads and your concentration on mountain paths. The counter-climb then arrives with both of those behind you.
The priorities follow from that. Long mountain runs with 600 to 800 metres of gain form the framework, ideally with the biggest climb placed after the first hour. Sustained steep sessions of 20 to 30 minutes build the fast hiking that pays more here than running. Add regular longer descents too, and finish some sessions with a short, steep climb to recreate the situation at km 14.
The date settles the rest: your main build falls in late autumn, the race in January, and over 700 metres of altitude separate the start from the high point. Put long sessions in the cold as well, test layers for both the climb and the descent, and try shoes with good grip on slippery paths. There is only one refreshment station on course, so practise carrying what you need.
