A record-breaking 75-mile GPS image of a penis has been scrawled across south Wales on the exercise app Strava to raise money for charity.

The outline of the male genitalia – drawn by the on-foot journey of Terry Rosoman – stretches from Hay-on-Wye to Abergavenny via a double circuitous route taking in Crickhowell and Llangenny.

It was completed in less than 24 hours by Rosoman, 38, a marketing director from south Wales, to raise money and awareness about men’s mental health issues for Movember.

He said he chose to run the giant phallus to help gain the attention of his “target demographic”. He claimed most men find the shape “hilarious”.

Rosoman began his journey with his friend Robin Hurst at 5pm on Friday at Abergavenny railway station and finished at about 4.30pm on Saturday at the same place.

Speaking afterwards, Rosoman said: “It was really tough. The hardest thing I’ve ever done in my life. It was just a hard slog for 24 hours.

“I didn’t sleep, I ran through the night, pitch black, I couldn’t see anything. We got lost loads of times.”

The route involved climbing 2,820m in total. Rosoman said: “The elevation killed us. It was really tough. I’m just glad to get it done.”

The Movember awareness charity campaign began 21 years ago as an annual sponsored moustache growing event, to raise awareness of men’s mental health, suicide prevention, prostate and testicular cancers.

By Sunday morning, Rosoman had raised more than £4,000 and is hoping to hit a target of £5,000.

He said the most difficult part was running in “12 hours of pitch black” through the night with little to no visibility because of heavy mist.

Rosoman said the highlight was crossing the finish line at Abergavenny railway station to see his daughters and wife, who “ran up and gave me a hug”.

He thanked those who joined him on his challenge and people who donated to his fundraiser.

“Just thanks for all of the support I got from people, everybody who came to run out with me, donated and shared,” he said.

Rosoman hopes his endeavours will inspire men to take on their own challenges.

“I just wanted to promote this message of challenges, essentially,” he said.

“Ultimately, it’s just about having aims, goals, but grand aims and grand goals that are bigger than yourself, that are more important than going to the pub, and it will give you that sort of purpose.”
