The Marcialonga track (which can be covered with cross-country skis throughout the winter season and on foot, with roller skis, by bicycle and on horseback in the summer months) crosses the entire
Fassa Valley and then
Fiemme valley: it is long, with a total difference in height of about . The average skiing time is about 3 hours and 13 minutes at an average speed of 21.5 km/h. The race starts from the so-called "plain" of
Moena, located at an altitude of above sea level, at the gates of the town near the municipal stadium. The morning start is one of the most spectacular moments of the competition and it takes place in line and in steps: the first to start are the "senators" (those who have participated continuously in all editions since 1971) together with the strongest professional athletes; at the center, the skiers who in previous editions have obtained a good placement; at the last, all the remaining amateur sportsmen, affectionately called "the
bisons". After the start, the track goes on the right bank of the
Avisio stream: the skiers face the first ascent towards the Moena Alpine Training Centre of the State Police and go up the whole Fassa Valley. Near
Soraga di Fassa, they cross the Avisio stream and reach
Vigo di Fassa where, in the locality of San Giovanni, there is the second climb, short but unequivocally nicknamed "legbreaker" (
Spacagiames in the local dialect). Then the race passez through the villages of
Pozza di Fassa,
Mazzin,
Campitello di Fassa up to the control point of
Canazei, at above sea level, where is located the first turning point. The trail goes back, finally downhill, from Canazei again till Soraga di Fassa, where skiers face the third climb, so called "The Endless" (''L'Infinita''), because of its length that requires considerable effort, considering that after the long descent from Canazei, the athletes' muscles have cooled down. Descending from the hamlet of
Someda, they cross the entire town centre of Moena, continuing straight on towards the next
Fiemme Valley. After passing the
"Giuseppe Dal Ben" Ski Jump Arena, skiers reach the town of
Predazzo, where there is the finish line of the half race (
Marcialonga light) near the former railway station. Arriving in
Ziano di Fiemme there is a short climb called
Diaol del Gaso, where athletes are warmly encouraged by the public. Once in the lower Fiemme Valley, the trail crosses the municipality of
Panchià and
Tesero (with a passage in the
Lago di Tesero Cross Country Stadium). After the waterfall (La Cascata) in Masi di
Cavalese, it is located the second point control point at
Molina di Fiemme, at the lowest altitude ( above sea level): here takes place the second turning point, back in the direction of
Cavalese. Returning to the "Cascata" (waterfall), it is where the stretch considered the hardest and most selective of the race begins: from there it starts the last of the challenging final ramp, called "Full Gas" or simply "ascent of the waterfall" (
salita della cascata), which with its 144 meters of elevation gain (with slopes of up to 12%) leads to the arrival in Mendini boulevard in Cavalese. At the finish line, the winner is welcomed with a laurel wreath. Along the entire route, in addition to the numerous fans and enthusiasts who encourage skiers, there are numerous resting points with free hot drinks and food, infirmaries, and technical areas equipped for waxing and replacement of damaged ski poles. Athletes who do not wish to reach the final finish in Cavalese can stop at the 45th km near Predazzo, where the finish line of the
Marcialonga light classification is located. In 2007, 2015, and 2017, due to the lack of snow, the race was shortened to 57 km (starting from Mazzin in the direction of Canazei and back to Cavalese), using of
artificial snow. The cost of the snowmaking program, which involves the production, movement and preparation of more than 70-80,000 cubic meters of snow, has cost about 200,000 euros in 2015: however, it has been estimated that the total turnover of the event amounts to about 8 million euros spent by participants, escorts and spectators. == Participants ==
