Resilience
Resilience is what gets you through those hard training sessions and races that just hurt. A lot!
Resilience is not about “Being Tough”. Almost every racer will have a cry during long races.
Resilience is about giving yourself 5 mins to cry and then getting on with the race.
Resilience is built up like an Onion of many layers. These have to be developed and trained over time. There are no shortcuts.
