The Helicon Skyrace is the long, ISF-certified course of the Helicon Mountain Race near Livadia. It climbs from the valley to almost 1,400 metres on Mount Helicon and back down again, and since more than half the distance is steep in one direction or the other, climbing strength and descending legs matter more than flat speed.
The loop starts at about 190 metres and gets serious at once: a first climb from km 0.3 lifts you just over 200 metres in under two kilometres before a short drop. From km 5.3 the real ascent begins in stages. Two long ramps take you above 900 metres by km 11, and after a brief level stretch the hardest section of the day starts at km 12.3, roughly 600 metres of climbing in three and a half kilometres up to the high point around km 16.
Then the race turns over. By km 22 you have lost almost 600 metres, and a short, very steep counter-climb from km 24.7 takes you back above 1,000 metres once more. From there the course falls for around seven kilometres to just over 330 metres, and that long descent is where the damage you did not feel on the climbs adds up.
The finish is no cool-down. Between km 34 and 36 two short rises add about 100 metres between them, and the last two kilometres drop steeply back to the start. The whole day is spent on Mount Helicon around Livadia, on a loop that starts and finishes in the same place.

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 Skyrace into two halves: uphill to km 16, mostly downhill after that. The first eleven kilometres are a warm-up whose gradients feel like racing; hike the steep parts early and deliberately, even while people around you are still running.
The race is decided on the big climb from km 12.3. At an average of about 17 percent it is half an hour or more of pure climbing work, best done at an even effort with hands on thighs. If you top out with enough left for the counter-climb at km 25, you control the day.
The main trap is the descending. Well over 1,000 metres of it lie ahead of you after the summit, the longest stretch between km 26 and 33. Let it run freely there and your quads will be gone for the two small rises just before the finish and the steep final drop.

For a typical age-group runner the Skyrace is an effort of roughly six to eight hours. Most of it is steady aerobic work, interrupted by long, steep climbs where heart rate is high and speed is low, and by long descents where the muscles work eccentrically.
The decisive sections ask for two abilities that are trained separately. For the big climb from km 12 you need power at hiking speed: hill efforts of 20 to 40 minutes on the steepest ground you can find, at a powerful hike rather than a run. For the long descents that follow, you need quads that survive many hundreds of metres of downhill.
So build long runs with a lot of vertical in both directions, and run the descents rather than walking them. Strength work for legs and core, especially eccentric exercises, is what separates controlled downhill running from stiff, braking steps in the closing kilometres.
An early April race date means most of your preparation falls into the winter months. Schedule the longest mountain sessions for February and March, and at least once rehearse a day where a long climb comes deep into the run.

Helicon Mountain Race is 38 km long. That distance shapes how much aerobic endurance, pace durability, and race-specific work belong in the training plan.
Helicon Mountain Race has around 2,037 m of elevation gain over 38 km. That affects pacing, muscular load, and preparation for late-race sections.
Helicon Mountain Race is classified as Mountainous, averaging 54.1 vertical metres per kilometre. 7% of the route is flat, 21% climbs moderately (2 to 6%) and 25% is steeper than 6%.
The hardest climb of Helicon Mountain Race starts at kilometre 12.3, runs for 3.6 km at an average of 17.3% and gains 617 metres. Cycling-convention rating: Cat. 2. 8 climbs are mapped in total.

Preparation for Helicon Mountain Race should account for 38 km, 2,037 m of elevation gain, current training load, and available training time. An adaptive plan helps place key sessions without ignoring recovery and real life.
The pacing strategy for Helicon Mountain Race should reflect 38 km, 2,037 m of elevation gain, and your current fitness. Start controlled and keep margin for sections where the profile or fatigue makes target pace harder.
