EX-Man United stars Nicky Butt and Ryan Giggs enjoyed pre-match beers before tackling the Three Peaks challenge.
Butt, 47, posted pictures on Instagram showing the group enjoying a pint, joking that Guinness and lager were “maybe not the right fuel”.
Best mate Giggs, 48, sat to the right of the group and kept a low profile under a woolly hat.
The challenge sees hikers walk 26 miles and ascend 9,843ft on Ben Nevis in Scotland, England’s Scafell Pike and Snowdon in Wales.
And the group now appear to have completed the challenge.
Butt provided regular updates of the group’s progress on his Instagram story, before posting a photo with the group at the summit of Snowdon.
Fellow ‘Class of 92’ member Paul Scholes posted a screenshot of Butt’s story which revealed they had completed the challenge.
Scholes, 47, accompanied his post with the caption: “Unbelievable lads… well done.”
The trio all played together for a number of years at Manchester United.
They graduated through the academy along with the likes of David Beckham, Gary and Phil Neville.

He faces a retrial over allegations of assault and coercive and controlling behaviour towards his ex Kate Greville, 38.
