All Parkrun events in Yorkshire have been cancelled
Parkruns took place last weekend with the initial indication that volunteers would try and keep them running as long as possible.
However, the more popular Parkruns can attract hundreds of runners and the decision has now been taken to cancel them until the end of March, with suspension into April more likely.
They have also asked runners not to arrange informal group runs at the usual venues.
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."
Parkruns in Leeds include Woodhouse Moor, Roundhay Park, Temple Newsam, Middleton Park, Armley Park, Rothwell, Cross Flatts and Potternewton Park. There are also popular events at Fountains Abbey, Harrogate Stray, York Knavesmire and Nostell Priory in Wakefield.
How can I exercise during the coronavirus pandemic?
The governnment has made it clear that outdoor exercise will still be permitted for those in self-isolation or quarantine. You can go for a walk or a run, but must avoid contact with other people while you are outside.
Many sports clubs, leagues and organisations have suspended organised activity, but there is some disparity between the governing bodies of different sports.
In Leeds, council-run leisure centres are closed from today but public parks such as Roundhay Park and Temple Newsam will remain open.
The National Trust has also committed to opening parkland and outdoor areas at its sites, although its buildings and facilities are now closed.
The guidance covering privately-owned gyms and sports clubs is unclear and many are still open.
