What racers and reviewers say
- Fiona Outdoors (Lexi Cremona)Raced 2016 · blog · Positive
Finisher account of a 49-minute tide-assisted swim, a 7h43 ride with about 3,000 m (9,843 ft) of climbing, and a cutoff-driven run to the high route. Praises the warm community, humorous briefing and the crew who paced and fed her. Moonlit mountain finish at midnight.
- Fiona Outdoors 2022 reportRaced 2022 · article · Mixed
Rough sea with big waves and dense jellyfish, strong crosswinds and headwinds on the bike, and sleet and hail on the run. Winds forecast up to 129 km (80.2 mi)/h (80 mph) led to the mountain being cancelled; 88 blue and 54 white shirts, 28 DNFs.
- Fiona Outdoors 2023 reportRaced 2023 · article · Mixed
Unusually hot, humid day with calm sea, few jellyfish, dry roads and light wind. A lightning storm hit Beinn Eighe during the run, forcing five course variations; only four completed the full high route.
- Carnethy HRC: The Celtman MachineRaced 2017 · blog · Positive
Crew-view account: cold rough swim with jellyfish, wet and chilly hilly ride with a punishing headwind on the return. High route cancelled for wind and rain. Calls it awesome but the crew vowed never to support again.
- Carnethy HRC: Celtman 2018Raced 2018 · blog · Positive
Athlete was surprised how enjoyable it was. Wetsuit coped with the cold jellyfish water, the support crew was essential, and bad weather closed the high route so he took the lower trail. Notes new trails that year.

- City of Lancaster Tri newsletterRaced 2025 · blog · Positive
Club member finished 2025 in roughly 10-11 C (50-52 F) water with jellyfish. Mountain rescue advised closing Beinn Eighe so no summit, yet the remaining run was still hilly. Described as one of the toughest long-distance triathlons.
- Slowtwitch 2015 race reportRaced 2015 · article · Positive
Describes an orchestrated mass start, quiet very hard bike roads, and an undulating run with a long climb and steep descent. Few spectators. Winners praised the beauty and brutality and the organisation; times 11:51 men, 14:01 women.
- Alligin Photography (Glasbrenner 2014)Raced 2014 · blog · Positive
Account of the first amputee finisher in 2014: 3.8 km (2.4 mi) cold swim, 202 km (126 mi) ride, then Coulin Pass and the two Beinn Eighe Munros with a punishing scree descent. Organisers and volunteers stayed to cheer the last finisher home after midnight.
- Border Telegraph (Iain Veitch)article · Mixed
Second-place finisher in 11:13:49 reported a very cold jellyfish swim, a bike with poor surfaces and headwinds, and losing the lead on Beinn Eighe. He considered the bike more damaging than the mountain.
- Coast.scot featureRaced 2021 · article · Positive
Local feature: swim from Torridon to Shieldaig at 5am, bike north past Gairloch and back via Garve and Achnasheen, run over Beinn Eighe. Residents were won over by participants from 40+ countries; midges and jellyfish noted.
