PDSA turns 100 this year - that's 100 years of saving pets and changing lives.
As we celebrate our centenary, we're encouraging as many people as possible to fundraise for us. What better way to celebrate our 100th birthday than by taking on an epic 100km challenge!
Action Challenge events are a series of 100km routes in some of the UK's most beautiful settings - from the stunning Jurassic Coast to the iconic Thames river. You can take part on your own or as part of a team and if you don't fancy the full 100km route there are shorter options available, too!
Take on the challenge and you'll be changing pet's lives.
