The 2021 competition has no set events due to the impact of the pandemic on running races. Rather, club members can pitch themselves against each other by entering their best times in 4 distances. Times can be over-written if you improve during the summer and members can enter times for any of the distances, you don’t have to run everything! Some of you have done qualifying 10k races already.
Information found under the WRC Summer Series menu. Second from the right at the top of the main screen.
