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:

Between them, these events required a serious amount of toilet power; a mix of portable loos, urinal units, accessible loos and a luxury toilet trailer.

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

Portable Toilet Hire for Half Marathons and Running Events 👟

Whether you’re organising a local charity 5K, a muddy trail run, a fast-paced 10K, a half marathon or a gruelling Ultra, portable toilets give you the flexibility to put facilities exactly where they’re needed. Typical locations include:

 

  • Start areas
  • Finish lines
  • Event villages
  • Registration zones
  • Spectator areas
  • Volunteer compounds
  • Medical and staff areas

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! 🌦️

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.

🏅 Why Event Organisers Choose LOOS FOR DOs

When you’re organising a major sporting event, you don’t want to be worrying about your toilets. You need them delivered on time, positioned where they’re needed and ready for thousands of users.

That’s where the #LOOCREW comes in.

“On behalf of ASO UK and the LDNX team, I’d like to extend a sincere thank you for your support at our inaugural event on Sunday. We truly appreciate the professionalism, quality of service, and flexibility you showed in helping us deliver the event to such a high standard—especially given the short timescales involved. I thought everything looked fantastic on the day.

Your contribution played a key role in making the event a success, and we are very grateful for your hard work.

Thank you again for your excellent work—we look forward to collaborating with you on future events.

“The Garden Shows began working with Loos For Dos in 2018 when the supplier we had at the time was unable to provide disabled loos and we were immediately impressed by their efficiency, professionalism and personal approach. We contacted LOOS FOR DOs in 2020. during Covid. when we needed to be absolutely sure that any facilities we provided to our shows were safely maintained and we were not disappointed. Their commitment to excellence was evident not only from their office staff but also from the crew responsible for delivering and servicing the loos at our events.

So we worked with them until 2024 when we made the mistake of switching to another supplier as we thought it was a good idea to go more local — a decision we quickly came to regret. We’re so pleased to be back with LOOS FOR DOs this year, and we have every confidence that we’ll continue working with them for many years to come. Simply put, they are the best.”

“Your guys are truly amazing … Marek, Damian, Tom…

They listen to what is required, do as requested, as it always changes every year, depending on the weather and condition of the field, work out the best way to do it, are polite, friendly and always work with a smile.

All these toilets are delivered down a single-track road and they are accommodating to other moving traffic coming in and out of the park and nothing is a bother to any of them.

You do really have a great bunch of men working for you and who are clearly proud to be part of your company.”
