Snowdonia Challenge

Early Bird tickets for Snowdonia Challenge 2019 available until 31st October 2018.

Snowdonia’s Unique Walking Challenge

The first Snowdonia Challenge was held in Betws-y-Coed, North Wales in 2017. The perfect base to explore some of the less visited parts of Snowdonia with some of the best views the national park has to offer.

Now in it’s third year this 3 day walking challenge is the only event of its kind in the UK! Not for the faint hearted, to take on the full challenge you will need commitment and determination to prepare for and complete this event.

The Snowdonia Challenge is a test of mental and physical resilience and team work and will take you on a journey of self discovery. It is inspired by multi-day challenges used as military training events in Europe.

This is not just about challenge and adventure though.  Taking part in the Snowdonia Challenge you will be part of an amazing adventure where you will make new friends and explore parts of Snowdonia you’ve never been before.

Full event – 3 day walking event – 100km over 3 days

Or if you’d like to be a part of it but can’t commit to the full 3 days then join us for 1 or 2 days.

Taking part

Each morning we start from the beautiful village of Betws-y-coed. On each day we follow a different route through the stunning Snowdonia mountains and forests starting from and returning to the same place each day.

Routes are well marked and marshalled along the way so no navigation is necessary.


If you chose to fundraise for your challenge you can take part in this event for a charity of your choice either as an individual or as part of a charity team.

If you have not yet chosen a charity you can join one of our partner charities when you book.


If you are a charity and would like to know how you can become one of our Charity Partners please contact us.

The Story

Snowdonia Challenge is inspired by an event held in Holland which started in 1909 as a  military training event and now attracts 46,000 military and civilian participants each year.

“I took part in Nijmegen Marches in 2009 and it was life changing. It took me on an incredible journey self discovery and proved to me what commitment and determination could achieve. I’m positive by taking part in Snowdonia Challenge you will experience the same range of emotions and feelings of personal achievement that I gained in 2009. I very much look forward to seeing you there and sharing this adventure with you.” 

Tracey – Breese Adventures co founder and creator of Snowdonia Challenge

  • All members of the team we met were very helpful and encouraging. This has been one of the most organised events I have taken part in, you seem to have got it almost right 1st time, well done.

  • This was such a fantastic event, tough enough to be a challenge for mere mortals, yet achievable to anyone with the determination to train and push themselves. It was also an emotional journey that will stay with me for a long time.

  • The challenge was so phenomenally well organised and you, Tracey and your whole team were absolutely brilliant. See you all next year!

  • Well done guys on a very successful Snowdonia Challenge 2017. Thoroughly enjoyed the whole weekend and cannot begin to thank you enough for such a well organised event. Every last detail was thought of and every person who formed part of the organisation for the weekend was knowledgeable, approachable and motivating! We met some fantastic people and made amazing memories. Thank you Tracey, Stiwart and team very very much. We wish you every success!!
