parkrun cancellations are decided locally, not by parkrun Ltd centrally. Each event has an event director who is responsible for the venue and the safety of participants. If they decide conditions are not right, they cancel. parkrun HQ is not involved in that decision.
This means cancellations can vary a lot. Two events five miles apart might have completely different decisions on the same morning. One has a flooded field and calls it off; the other is fine and goes ahead. There is no blanket national cancellation system.
We track every UK cancellation week by week. See the full cancellation data, including how often each reason comes up.
The most common reason. The landowner withdraws permission, the park is closed for an event, or there is a clash with another booking.
Flooding, fallen trees, ice, mud, or other hazards make the course unsafe to run. Usually a weather-related call.
parkrun requires a minimum number of volunteers to run safely. If not enough people have signed up, the event cannot go ahead.
Bank holidays, local events, or pre-arranged venue maintenance. These are usually known weeks in advance.
It varies enormously. Planned cancellations - where the venue is unavailable due to a pre-booked event or annual closure - are often posted to the parkrun website days or even weeks ahead. You have time to plan around them.
Weather-related cancellations are different. If there is a storm on Friday night or a hard frost on Saturday morning, the event director might make the call at 6am or 7am - less than three hours before the start. By then, some people are already in their cars.

The problem with finding out last-minute: the official parkrun cancellations page is updated, but most people do not check it before they leave. They find out when they arrive and the field is empty. SaturdayOff exists to fix this - sign up below and we will email you late on Friday night or first thing on Saturday if your event is cancelled.
We check the cancellations list late on Friday night and again first thing on Saturday morning. If your parkrun has been called off by then, you will hear from us before you head out.
There are three reliable ways to check:
Your Saturday morning does not have to be wasted. A few options:
No. If an event does not take place, nothing is recorded. Your total runs, milestone progress, and age grade history are unaffected. Only completed, scanned runs count.
Yes, and it happens more often than you might think. A storm rolls through overnight, the course floods, and the event director makes the call at 6am or 7am Saturday morning. By the time the cancellations page is updated, some participants are already travelling.
This is why getting an alert matters. The window between a last-minute decision and people arriving at an empty park can be very short.
SaturdayOff course guides are written by runners who actually know the event. If you run somewhere regularly and want to share what you know, we would love to hear from you.
