Walkers are being urged to sign up and be part of the 35th Waendel Walk.
Advanced registration is now available for the International Waendel Walk weekend, which is taking in Wellingborough from May 9 to May 11.
The annual event attracts thousands of walkers from all over the world, and anyone wanting to book their place in advance has until Thursday, May 8, to register.
The Waendel Walk is the only event of its kind in the UK and will kick off on the evening of Friday, May 9, with two friendship walks of 5km and 10km.
They will be followed by a weekend of different routes throughout the borough, ranging from 5km up to a marathon-distance of 42km.
Cllr Peter Morrall, chairman of Wellingborough Council’s community committee, said: “I’ve been involved in the Waendel Walk for more than 30 years now, and over that time I’ve seen it grow hugely in popularity and size.
“What we now have is a truly international event, attended by four or five thousand walkers from every corner of the globe, including as far away as China and Japan, as well lots of people from much closer to home.
“We’re always told how much everyone enjoys taking part in the walks, not only because they’re safe and very professionally organised, but also because of the stunning countryside that so many of them pass through.
“Even people from right here in Wellingborough are often amazed to be exploring the beautiful scenery we have right here on our doorstep.
“The Waendel Walk also has such a positive effect on our local economy, with hotels, guest houses and shops all getting a big boost in trade.
“It’s a perfect opportunity to showcase to people all over the world what our borough has to offer.”
Pre-booking to take part in the Waendel Walk is cheaper and will avoid queuing on the day.
People can register via The Castle theatre’s website until Thursday, May 8, after which people will have to register in the main hall of The Castle.
