Wetsuit outlook
Will you need a wetsuit at Cholmondeley Castle Triathlon & Multisport Festival?
Water temperature at inland lake in June has typically been 13.7°C, ranging from 12.4°C to 15.6°C in eight of every ten years. Against British Triathlon's thresholds for this race's 1500m swim, that means:
Wetsuit mandatory
Below 14°C a wetsuit is compulsory for a 1500m swim under rule 4.2(a).

What the organiser says
Not confirmed in sources checked — check the official Castle Race Series page for the current rule.
Estimated from air-temperature history — no direct measurement of this water exists, and small, shallow venues tend to run a degree or two warmer than shown. The official temperature is taken an hour before the start, and only that reading decides the rule on the day.

Where Cholmondeley Castle Triathlon & Multisport Festival starts and finishes
Cholmondeley Castle Triathlon & Multisport Festival starts at Cholmondeley Castle, near Malpas, Cheshire and finishes at Deer Park Mere, Cholmondeley Castle. We haven't been able to place those on a map accurately enough to show one — a pin in the wrong place is worse than no pin.
These are the start and finish points, not the route. Verus doesn't hold course files for this race, and drawing a line between two pins would be a guess you might end up training on. The official course map is the one to use: view it on the organiser's site .
