Challenge walks in the UK range from anything over half marathon distance (13+ miles / 20+ kilometres) right up to ultra challenges over either a single day, weekend or longer.
They could well involve some undulations but aren't geared around a summit target.
You'll have plenty of time to talk to and support your fellow walkers - and many of the challenges are guided so you can focus on your surroundings.
Many of these are perfect for team-bonding days out or weekends away - look for 'suitable for teams'.
Do something different
How about a night-time walking adventure? Or if you want to be even more energetic you can jog or run some of the longer walking challenges.

ESSENTIAL INFO
Training advice
"The more you train, the more you'll enjoy it. Try and work it into your everyday routine - walk to and from work or get off a stop early," says endurance walker David Wilson.
Training advice
In your rucksack
It will depend on the nature of your walk but map and compass, waterproofs, hat and gloves, plus plenty of food and water (if not provided) are the essentials.
Be prepared
Keep a close eye on the weather, especially if you are on a long distance walk - and hydrate accordingly.

Walk for longer
"Poles are like a four-wheel drive for humans and by distributing the weight between the upper and lower body muscles you can walk for prolonged periods of time," Dave Cheetham, Plas y Brenin National Outdoor Centre, whose intructors use LEKI poles.

Tips from the pros
"The trick is to start cold and walk warm, meaning don’t over-layer at the start of the walk when you get out of a warm car into chilly air," says Jo Bradshaw, challenge leader for Discover Adventure - and successful Everest climber.
