How many challenges are planned every winter?

Up to 30 challenges can be launched between December 1 and March 30, week days and weekends alike. They’ll be carried out mornings, from 4:00 a.m. to 11:00 a.m., or at the end of the day, from 3:00 p.m. to 10:00 p.m. It is thus possible that a day includes:

  • no challenge
  • only one challenge in the morning
  • only one challenge in the evening
  • two challenges: one in the morning and another in the evening
