Callum Rowlinson took victory at the Scott Snowdonia Trail Marathon, while GB mountain-running international Emma Clayton won the accompanying half-marathon event on Sunday.
Rowlinson completed the tough course in three 51 minutes 42 seconds, crossing the finish line in Llanberis nearly three minutes clear. Leading woman Jo Meek was ninth overall in 4:10:36.
Elliot Cox was first finisher in the half-marathon, clocking 1:52:57 to cross the line 22 seconds ahead of runner-up Jezz Bragg.
Clayton, who won bronze in the 2015 European Mountain Running Championships, was well clear of the rest of the women as she ran 2:15:44.
More than 600 completed the marathon and a further 500 the half-marathon event. The marathon route, which involved 1685m of ascent, circumnavigated Snowdon before taking the runners to the peak of Wales' highest mountain. The half-marathon took the Snowdon Ranger route rather than the Pyg track to the top.
A spokesman for organisers Always Aim High Events said: “The 2017 edition of the Snowdonia Trail Marathon was by far the biggest race in its three-year history, and now already ranks as one of the largest and most challenging trail races in Europe. 2000 runners have experienced Snowdonia National Park in all its glory today - the weather really showcased what makes this area of the world so special - people are already booking accommodation for next year!
“With over 40 countries represented this year, it’s one of the few events in the country that can legitimately be labelled an international race.
“We’d like to thank our race partners, Gwynedd County Council and all the locals and event marshals that made the race such an incredible experience.”
Entries for next year's event, which will also include a 60km ultra, open on July 26.
