22nd May: Spencer Matthews has completed his toughest UK endurance challenge to date, successfully conquering six full ascents and descents of Snowdon in 22 hours and 41 minutes, fully on foot, and in some of the mountain’s harshest conditions.

Spencer battled relentless climbs, exhaustion, darkness and wind speeds exceeding 60mph, while relying on O2 Satellite to stay connected with his support crew and family in areas beyond traditional mobile coverage.

The challenge began at 10am on Thursday 21st May, with Spencer set the goal of taking on six of Snowdon’s most iconic routes: Llanberis Path, Rhyd Ddu Path, Pyg Track, Miners’ Track, Ranger Path and Watkin Path, in less than 24 hours.

Throughout the challenge, Spencer was supported by O2 Satellite, using the service to navigate in real time, access live weather updates, share his location and stay in touch with his support crew and family across isolated mountain terrain beyond traditional mobile coverage.

The feat is the latest in a series of extreme endurance challenges for Spencer and reunited his PROJECT 7 team – which saw Spencer complete seven Ironman-distance triathlons on all seven continents in just 21 days.

Spencer Matthews said:

“I’ve taken on some tough challenges over the last few years, but this was one of the toughest days I’ve faced. A knee injury on the second descent made it difficult to predict the outcome and high winds and difficult terrain made for unfamiliar territory.

“The climbs were relentless and there were moments overnight where exhaustion created a negative headspace. But meeting great groups of people along the way, and becoming more familiar with Snowdon, made it incredibly rewarding.

Having O2 Satellite throughout the challenge also gave me real reassurance and a huge mental boost, knowing that we were always connected and therefore, safe.”

Chris Bournes, Commercial Director at Virgin Media O2, said:

“What Spencer achieved on Snowdon was extraordinary. Throughout the challenge, O2 Satellite was tested in exactly the kind of remote and demanding conditions it’s designed for, helping Spencer stay connected with his support team and loved ones when traditional mobile coverage wasn’t available. Whether sharing his location, checking changing weather conditions or simply staying in touch during the toughest moments overnight, the technology gave him vital reassurance during an incredibly punishing endurance challenge.”

O2 Satellite is the UK’s first and only fully launched satellite-to-mobile service, helping bring connectivity to places beyond the reach of traditional mobile networks.
