Marathon Temporary Mobile Toilets

The planning of temporary mobile toilets for marathons requires comprehensive consideration of participant traffic, venue conditions, and event requirements, ensuring a good user experience and event order through scientific calculations and reasonable deployments.

1. Calculation of Toilet Seat Numbers and Regional Allocation
Toilet seat planning takes the peak number of participants, distribution of race course refreshment stations, and average usage duration as core parameters. At the start and finish areas, due to the concentrated arrival and departure of runners, a higher proportion of toilet seats should be allocated, such as one toilet seat per 50-100 people, to meet the high-frequency usage demands in a short period. Along the race course, mobile toilets should be set up every 2-3 kilometers in combination with the distribution of refreshment stations, with each group containing 3-5 toilet seats, ensuring that runners can use the toilets in a timely manner during long-distance running.

2. Selection of Mobile Toilet Types

• Flush Type: Relies on external water supply and sewage pipe networks, suitable for urban centers or venues with well-developed infrastructure, but requires advance planning for pipeline connections and has relatively high cleaning and transportation costs.
• Waterless Packaging Type: Encapsulates waste with biodegradable materials, reducing water dependence, suitable for remote areas or temporary venues, but requires regular replacement of packaging bags and has a lower frequency of cleaning and transportation.
• Vacuum Suction Type: Uses negative pressure technology for efficient waste disposal, saving water and having excellent odor control, suitable for long-duration events with high environmental hygiene requirements, but has relatively high equipment costs.

3. Deployment Location and Safety Requirements
Placement points should avoid timing equipment, medical stations, and main runner circulation routes to prevent cross-interference of pedestrian flows. At the same time, transportation channels should be kept clear to facilitate the entry and exit of subsequent maintenance vehicles. For night events, sufficient lighting signs should be set up around the toilets to prevent accidents caused by poor visibility of runners. The ground conditions should be flat and solid to prevent equipment tilting or damage.

4. Technologies for Optimizing User Experience
Ventilation, deodorization, and anti-slip measures are key aspects. New equipment improves air circulation by adding top ventilation windows, uses microbial degradation additives to decompose odors, and lays anti-slip floors to reduce the risk of slipping. Some high-end models are also equipped with warm air systems and automatic flushing functions to further enhance comfort.

5. Cleaning, Maintenance, and Resource Allocation
Before the event, equipment inspection and initial cleaning should be completed. During the event, circular cleaning should be arranged in different zones according to usage intensity, with a focus on cleaning high-frequency contact areas such as door handles and flush buttons. The timing for emptying waste collection boxes should be predicted through load monitoring to prevent overflow. The command center can rely on real-time data to dynamically adjust the deployment of cleaning personnel or alleviate queuing pressure by adding signs or deploying spare toilet units.

6. Historical Cases and Lessons
In the 2026 Harbin Marathon, toilets were used for shelter from the rain, leading to runners relieving themselves on roadside lawns. In the 2013 Beijing International Marathon, unreasonable toilet locations and a lack of guiding signs led to collective public urination incidents. These cases highlight the importance of reasonable planning and dynamic management.
