What racers and reviewers say
- Racecheck: Eastbourne Triathlon and Multisport FestivalRaced 2026 · aggregator · Positive
206 ratings, 4.83 average, 2016 to 2026, Gold Awards in 2019 and 2022. Reviewers agree on excellent organisation, a festival atmosphere and a beautiful bike route past Beachy Head. The bike is hilly (86% of reviews) and the run flat and fast (87%). The sea swim is a known variable: swims were cancelled in 2024 for wind and one Olympic finisher disliked the dull run doubled up as a duathlon. 58% say ideal for beginners.
“Really well organised, with a great vibe”
- Brighton Phoenix: Erica Martin account of the Eastbourne TriathlonRaced 2016 · blog · Positive
Club newsletter report from an age-group winner: first sea swim in a race with a very strong current, an undulating bike loop around Beachy Head with a flat seafront return, and a run with a steep climb (an older routing). Chip timing missed her run split. Recommended it as well organised and challenging.
“well organised, challenging and local”
