The Parkrun in Omagh has cancelled its Saturday morning run in line with the global organisation's response to the coronavirus pandemic.
Parkruns took place last weekend with the initial indication that volunteers would try and keep them running as long as possible.
However, the decision has now been taken to cancel them until the end of March, with suspension into April more likely.
A statement from Parkrun said: "In line with public health advice, we have taken the decision to close all Parkrun events across the United Kingdom with immediate effect. Initially, this closure will be in place until the end of March, however this is largely to bring all Parkrun countries into the same time frame and we very much expect closures to continue through April at least.
"Going forward we will update Parkrunners regularly and aim to communicate important information as soon as is appropriate.
"We know that this message may be a difficult one for you to receive, and many people will be wondering what to do without their regular weekly catch-up. Please rest assured that we are working hard to develop our strategy so that we are able to support the health and happiness of Parkrunners around the world during this difficult time.
"Remaining active is incredibly important, and we are working on ways to encourage and support that, however please do not arrange group gatherings at your Parkrun venues whilst Parkrun events are suspended."
