Course & challenge

Serra de Tramuntana (SDT)

The SDT crosses almost the whole range, overnight first. From the cove at Cala d’Estellencs it climbs through the village of Estellencs onto the Camí des Correu to Esporles, then runs on through Valldemossa, Bunyola, Orient and Alaró, past the Tossals Verds, the area around the Lluc sanctuary and the Cúber reservoir, with Puig Major, the roof of Mallorca, in view from the high point, and down through Fornalutx to Port de Sóller. The organiser gives 5,350 metres of ascent and the same in descent.

Assistance is allowed only at the Alaró aid station and the Lluc aid point, by one person with a bag of no more than 30 litres. Each runner has an official drop bag for each of the two. The time limit is 30 hours 30 minutes. Finishers earn 4 Running Stones, and the top three men and women qualify directly for UTMB Mont-Blanc.

A 22:00 start means the first stretch is followed in the dark. On the runner’s Livebib link, family and friends see the position on the course, the distance covered and a finish estimate for Port de Sóller that updates through the night and the next day, including when the crew should be at Alaró or Lluc. When the phone loses signal in the mountains, the position carries on along the course, marked as estimated.
