"This suspension includes all organised athletics activity within the UK, including competitions and leagues, member clubs, running groups and races.
We are advising that clubs and groups should not be undertaking training, competitive or other related activities during this period, and it is already apparent that parts of the sport are already showing their own leadership and are acting in this respect.
Other suspended activity includes, but is not limited to, coaching, officiating, education and qualification courses and athlete development activities"
That'll be the end of parkrun who were still stalling and had promised a decision by tomorrow last I heard.
