Take on the ultimate triathlon!
We're challenging you to swim 2.4 miles, cycle 112 miles and run 26.2 miles in seven days.
Choose your Will of Iron week today
The only event of its kind, Will of Iron can form part of your training for something bigger or be a stepping stone to your first triathlon.
You can take part at the gym or outdoors, solo or as part of a team. Your team can be two people or as many as you like, there's no limit. You and your teammates can each pick a discipline (cycling, swimming or running) or choose all three and divide the distance.
Do as much or as little as you like and still call yourself a triathlete! All you need to do is complete the distance over seven consecutive days.
We can’t wait to have you on the team!
Willow is the only national charity supporting seriously ill 16 - 40 year olds to fulfil uplifting and unforgettable Special Days. A Special Day is so much more than just a day. It's hope, happiness and support when it's needed most.
Every penny you raise will help create more Special Days for seriously ill young adults. Thank you.
