What racers and reviewers say

  • Tri247 - Paul Hayward on the SlatemanRaced 2017 · article · Positive

    A 2017 finisher calls the event epic and not easy: a cold Llyn Padarn swim, a bike that climbs straight out of Llanberis and a trail run that he found brutal. He found the Snowdon views so absorbing he forgot photos and praised the crowds and volunteers. Covers the original Slateman before the Legend existed.

    “brutal and beautiful”

    Paul Hayward
  • Always Aim High Events 2023 race reportRaced 2023 · article · Positive

    Organiser report on the 11th Slateman: hot and sunny with a noticeable headwind on the bike, humid on the Sunday. The Legend bike was 92 km (57 mi) of passes with steep climbs and fast descents; the run was two laps with two quarry climbs. Legend winner took 4:45:47.

  • Always Aim High Events 2026 race reportRaced 2026 · article · Positive

    Sunday started overcast but calm and turned beautiful. Legend winners finished in 5:13:57 and about 5:46:55; slowest finisher still raising money in fancy dress at 6:57:51. Promotional, upbeat tone about the atmosphere.

  • Let's Do This event listing (via search summary)Raced 2023 · aggregator · Positive

    The 2023 listing showed a 4.9 out of 5 average across 5 reviews. Tiny sample and not Legend-specific, so only a loose indication of satisfaction.
