action challenge

.. and we bring people together through challenge & adventure


Since 1999 we’ve organised inspirational challenge events & adventures in the UK and Worldwide, for individuals to join, and for groups, companies & charities. Take on a challenge just for yourself, or link it to a special cause & fundraise – and so far our events have raised nearly £100 million for charities. Now is a great time to set new goals, to re-energise, and to get active!


challenge youreslf with like minded adventurers

We have over 40 UK & overseas challenge events that you can sign up to – ranging from a meandering 25km Thames Path walk, exploring Machu Picchu, to conquering a snow capped Himalayan peak. Group adventures with full support all the way; make new friends and push yourself further! We welcome individuals, couples, or groups of friends & family – and you can self-fund just like an adventure holiday, or link your challenge with fundraising for a charity of your choice. 

groups & Teams

Unforgettable challenges that bond & build

Few experiences bring a group closer together than an outdoor adventure which tests comfort zones, builds understanding & resilience, and forges respect & friendships. If you have a small group you can join one of our 40+ scheduled events – or if you have a larger group or want something special – we can craft a bespoke tailored itinerary, or plan a unique challenge event from scratch in the UK or overseas to meet your objectives.


Join us on one of our UK Ultra Challenges, get active and kickstart your training with a free 50km entry worth £139.

Corporate Challenges

Motivation. Wellbeing. Engagement. CSR

Energise colleagues, boost wellbeing, engagement & loyalty, and ensure CSR objectives are on-track. We’ve planned & delivered many amazing corporate challenges – from taking Harrods, HSBC, Blackrock, DHL, Citibank to Kilimanjaro’s summit; groups from British Gas & WPP on grand cycling tours; to hundreds of Tesco trekkers relaying the full length of Britain. Whatever challenge your organisation is looking for – UK, Europe, overseas – mass participation, small group, or even a company wide ‘virtual event’ – we can make it happen!

Open Evenings

Hear more about one of our challenges – we run regular open evenings for a selected range of trips – either online, or you can join our team in-person. The sessions last for around one hour, and include time for any questions you might have – PLUS there are exclusive discounts.

Charity Challenges

We can help boost fundraising & loyalty

We deal with over 400 UK charities of all sizes, and our challenge events have helped raise nearly £100 million for good causes. Whether it’s the UK’s biggest & best series of walks & runs with our famous Ultra Challenges, or because we’ve taken over 5,000 trekkers to the summit of Kilimanjaro, or that you want innovation & inspiration for your own bespoke challenge – we have the range of events, the experience, the track record, and the passion to help your charity with a fundraising challenge.

The UK’s best loved & biggest series of walking & running trail challenges –  with 30,000+ adventurers taking part each year and raising over £7 million for over 400 charities. In 2023 we have 15 fantastic events across the country that your charity can promote to your fundraisers & corporate partners.

We have 40+ events & adventures  across UK, Europe, & overseas that your charity can promote to your supporters as amazing fundraising challenges. They’ll get full support all the way, with UK mountain leaders & medics on our tough overseas treks – and you’ll have the confidence of dealing with a first class operator that has over 20 years experience within the charity challenge sector.

Many charities want their own special ‘bespoke’ trip – tailored for their supporters to act as a focal point for a major fundraising initiative – and we’ve organised hundreds of successful, unique, challenges. Whether it’s a trek, cycle, community project, or mass participation event – in the UK or abroad – our Team will deliver the perfect event, which your charity will be proud of, and will inspire your supporters!

We have a flexible platform which facilitates any form of virtual challenge for our clients – whether it’s walking, running, cycling, climbing, swimming, or even haircutting! An engaging virtual challenge could be a great addition to your charity’s fundraising program – and we can deliver it.
