How's your fitness?

Whether this is your first marathon or your hundredth, we're here to support you all the way up to when you cross the finish line. If you want it bad enough, anyone can run a marathon and batter a PB (especially with the HA training plan).

No Marathon Experience?

50% of our runners are first time marathon runners. Being in a group of others in the same boat makes the journey so much more enjoyable, from meeting up for runs pre-adventure to collecting your medals together.

Coming Solo?

75% of our participants come solo! But you’ll leave with mates for life.
Each team is made up of 40+ other participants, and a Hardest Adventures rep.

Age Requirements:

All Paris runners must be at least 20 years of age by the end of 2026.
All Lisbon runners must be at least 18 years of age by race day.
