Walking 268 miles across moors and bogs along Britain’s toughest and oldest National Trail - and climbing higher than Mount Everest in the process - is not easily forgotten.
But just in case anyone needs reminding that they have completed the Pennine Way, they can now have their own, personalised certificate.
There is a range of options available from a glossy certificate featuring Stoodley Pike for £4 to a simpler design that can be printed at home for free after completing a short survey about the trail.
The information taken from the survey will go towards making the trail better for future walkers.
There is also a new range of merchandise available to buy, with proceeds going to the upkeep of the Pennine Way.
Trail Officer Heather Procter said: “It doesn’t matter when you walked the trail, or whether you completed it in one go or over a number of attempts.
“Each certificate is personalised with your name and the date you completed it.”
Certificates are also available to those who complete the Pennine Bridleway, a 205 mile trail for walkers, cyclists and horse riders that runs parallel to the Pennine Way.
The trail is a huge undertaking, it is usually walked over 16-19 days and the total ascent is 40,000 feet, which is higher than Mount Everest.
It runs from Edale in Derbyshire to the Scottish border town of Kirk Yetholm, with the route passing by Hebden Bridge Blackshaw Head and Todmorden on its leg through Calderdale. For more information on the certificates for the Pennine Way and Bridleway visit www.nationaltrail.co.uk/pennine-way
