“unforgiving but fun hilly bike”

Poor water conditions after heavy rain led to the swim being cancelled; triathletes did duathlons instead. The Olympic became a 5.2 km (3.2 mi) run, 40 km (25 mi) bike and 10 km (6.2 mi) run for over 500 athletes. Organiser says athletes adapted well.

“electric”
- Castle Race Series: Hever Castle 2022 reportRaced 2022 · article · Positive
Season-finale report after Friday downpours; the weekend was dry and cool. Describes undulating Kent bike roads, laps of the grounds on the run, record numbers and a festival feel with live music. Says the shorter sprints suit newcomers.
- Racecheck: Hever Castle Triathlon SeriesRaced 2014 · aggregator · Positive
Rated the event very highly: superbly organised, easy sign-up and quick registration, grass racking and a good briefing. Warns the swim is cold, the bike hilly on small unclosed roads, the run mixed with a steep first 500 m (1,640 ft) and gravel, and the car park is about a 15 min (1 km (0.6 mi) / 0.6 mi) walk from registration.
“superbly organised”
