HAC caters to the novice, the weekend athlete, the hardcore adventurer, the endurance champions and even the family; making it India's premier team racing event.

Our Associations so far


We started as a fundraiser to bring people to travel back to Uttarakhand. The Himalayan Adventure Challenge (previously known as The Aqua Terra Challenge) was set up to remember the June-2013 flood victims of Uttarakhand, and sought to bring people back to this beautiful part of India. Aquaterra Adventures along with Atali Ganga supported the event to help bring back opportunities, choices, resources, essential services into the lives of many in Uttarakhand. The event was spread over 45 miles, and 2 days of challenge, involving a time based gruelling walk followed by a 16 mile cycling leg to the third and very exciting leg of the event – a 15 mile raft / inflatable kayak race down the mighty Ganges.
The event has since then taken place each December on the Ganga River at our base Atali Ganga, 30 Kms upstream from Rishikesh. Now, we sponsor team members (free of cost) which are made up of budding youngsters from the villages in the region and from Rishikesh. Quite a few of them have gone on to win multiple race events along with many prizes.
With HAC's fifth edition successfully taking place in December 2021, a new challenge is born and the first edition on the Tons river takes place this Summer at our picturesque beach front property; Camp Bagi, only 410 kms from Delhi. We also continue the tradition of encouraging the youth of Uttarakhand and will sponsor more children (boys & girls) to take part in this challenge with the rest of the participants.

We use a points system where times get adjusted for age and gender. This is based on age/gender adjustments for qualifying times used by international marathons of Boston, London and New York. The time to complete HAC of every individual team member is taken and adjusted. The individual adjusted times are then totalled to give the final adjusted team time. This is then used to decide HAC winners and runners-up. It means people of any age or gender have just as much chance as anyone else.
