Help us raise £50,000 for Nepal Earthquake Appeal

Nepal Ultra       

Join us and help raise £50,000 for the Disasters Relief Committee Nepal Earthquake Fund. We're giving away 100 free places to anyone who wants to take part in either our Grand Union or London 2 Cambridge Challenge, and who can raise £500 for the appeal by the end of July. We've already had participants take on the London 2 Brighton Challenge, so well done to them and good luck with the rest of their fundraising!

Action Challenge have been running and operating trekking challenges in Nepal for over 15 years and whilst we did not have any clients in Nepal at the time of the earthquake we are hugely concerned for our teams on the ground of operators, trekking guides, cooks and porters who we have worked with over the past few years. We have been hugely fortunate to be able to offer fantastic challenges to our participants over the past years through the hard work, dedication and passion of the local teams. They have enabled us to take 000's of challengers on life changing adventures; trekking to Everest Base Camp, through the Annapurna region and sight seeing in Kathmandu - and we are committed to ensure that we can raise as much as possible for our UK based challenges now to raise vital funds for this Relief Fund. 

So join us on our 100 km walk or run in either June or August - and raise as much as you can (with a target of £500 by the end of July) and we will give you a free place on the event to aid you with that fundraising. 




Training Walks & Weekends

One of the best ways to get ready for the challenge, is by taking part in one or more of our organised training walks. Get the 'feel' for the challenge ahead and build up that base level of fitness!

Led by experienced Action Challenge leaders, these training walks are also an excellent opportunity to get advice on training, equipment and nutrition - as well as meeting like-minded 'action challengers.'

London Day Walks

  • 7 June 2015

Our London Training Walk! Leaving from a Central London location, we will follow 18 miles of the Thames Path Trail, heading for Richmond. The fairly flat path will aid your training in your kit, equipment and give you the chance to test out your pace, fitness and emulate the experience of being on your feet for a long distance. As a walk to kit start your training regime this is a perfect way to get you going and meet fellow challengers as you walk.

ETA Start: 09:00 ETA Finish: 15:00 -18:00

London Night Walks

  • 18 April 2015
  • 9 May 2015
  • 11 July 2015

Taking the London Thames route and setting off between 11 pm - and midnight there is no better way to practice the night time walking sections of the challenge then to get out there and walk at night! Lead by our experienced guides, head torches - the aim of the night training walk is to get your body and mind used to the slightly surreal experience of walking for a long period of time at night - when your body wants to be resting.

ETA Start: 00:00 ETA Finish: 05:00 -07:00

North Downs Day Walks

  • 2 August 2015

This walk begins in Guildford, climbing from the town via the Riverside Walk. From here you will pass in and out of the woods and through the beautiful county of Surrey Hills, offering beautiful views over the Valleys to the South, before eventually reaching Denbies, Dorking.

ETA Start: 09:00 ETA Finish: 16:00

South Downs Day Walks

  • 22 February 2015
  • 31 May 2015
Our particular training walk follows part of the National Park’s 100 mile trail, from Clayton to Southease, traversing Ditchling Beacon and stretching over a rare large area of outstanding natural beauty. The South Downs Way is a fantastic and challenging training walk
ETA Start 09:00 ETA Finish: 16:00




Training Weekends

219x198 Iow Walkers

Our training weekends are the best way to prepare yourself physically and mentally prior to tackling one of our Challenges, and they are a great way to meet other trekkers, the Action Challenge team and our fully qualified Mountain Leaders.  They're also a brilliant excuse to also test out your kit and equipment on a mountain, against the elements!

We have a number of Training Weekends in the Peak DistrictSnowdonia and the Breacon Beacons spread across the year, from early Spring until September, so there should be a weekend to suit you. We also run Snowdon Night Time Summit weekends to replicate summit night on Kilimanjaro.

Congratulations Trekkers!

Congratulations to our New Year Killi Climbers! 

As the sun dawned on a new day and year on the morning 1st January 2015 - our group of 25 intrepid trekkers successfully reached the summit of Kilimanjaro - seeing in the New Year from a different perspective! 

New Year Kili News Story


After setting off from London on boxing day - opting for fresh air and trekking over another box of Quality Street and Dr Who re-runs - our group took on the 6 day Machame route up to the summit. Blessed with good weather and great views of the summit it is an experience not to be forgotten.

 "I loved every second and never had a down moment. I doubt I will ever top this!"

If perhaps you have the January blues and are keen to take on Africa's tallest mountain to see in the next New Year - sign up to our 2016 New Year summit!
