The Helly Hansen Killarney Adventure Race took place at the weekend in Killarney National Park.
More than 1,800 athletes competed in the gruelling multi-activity race, and could choose from three race distances (69k, 59k and 27k).
Participants faced many challenges, including mountain runs on Strickeen Mountain, Mangerton and Torc mountains; cycling through the Gap of Dunloe, Black Valley and Molls Gap; kayaking on Muckross Lake; and cycling though the oak woods of Muckross Peninsula, finishing at The Gleneagle Hotel, Killarney, for an epic aprés adventure party.
The hardcore athletes competing in the 69k and 59k races began their adventure at Kate Kearney's Cottage, running up Strickeen Mountain.
Then it was on their bikes, heading through the Gap of Dunloe, down to the Black Valley and up to Molls Gap.
Participants then ventured into kayaks on Muckross Lake.
The 69k race climbed up the Torc steps and climbed on to Mangerton Mountain with a rise of 839m, while the 59k climbed Torc Mountain (470m).
The 27k race included cycling 11k through Muckross and Killarney National Park, kayaking Muckross Lake for 1.5k, and a Torc mountain run with a 8k lead up the mountain from the Torc steps, and finally a 4k cycle back to the Gleneagle Hotel.
Race director Ollie Kirwan said: "It's all down to the wonderful athletes who make the event such a success.
"We are so grateful the day stayed so fine and racing conditions were perfect."
