Fresh from another brilliant weekend supporting the Ealing Half Marathon and Windsor Half Marathon, we’re taking a look at one of the most important parts of race-day planning…the loos.
On Sunday 27th September, the #LOOCREW were proud to support two of the UK’s most popular running events:
- Ealing Half Marathon at Walpole Park đââď¸
- Windsor Half Marathon at Windsor Great Parkđł
When thousands of runners, spectators, volunteers and event staff gather in one place, having enough loos isn’t just a nice-to-have. It’s essential for keeping the event running smoothly from the first warm-up stretch to the final finish-line sprint.
Anyone who’s ever taken part in a running event knows the pre-race loo queue is almost as much of a tradition as the start line itself!
The challenge for organisers is keeping those queues moving. The right number of toilets in the right places helps reduce waiting times, improves the runner experience and takes pressure off event staff on the day. Unlike many outdoor events, running races tend to experience intense periods of demand. Large numbers of participants often arrive within the same time window, creating a significant rush for facilities before the race begins.
How many toilets do I need for a running event?
It’s one of the most common questions we get from race organisers and, unfortunately, there isn’t a one-size-fits-all answer. The right number depends on:
- Number of participants
- Expected spectator numbers
- Event duration
- Availability of permanent facilities
- Accessibility requirements

The One Thing Nobody Can Control
Both Ealing Half and Windsor Half are always a pleasure for the #LOOCREW. The organisers are fantastic to work with, the planning is spot on, and site access is refreshingly straightforward.
The only wildcard? The British weather! đŚď¸
Late September can deliver glorious autumn sunshine, torrential rain or a bit of both before lunchtime. Thankfully, with good planning and a flexible team, we can keep things moving whatever the forecast decides to throw at us.
