Parkrun's fifth birthday on Saturday included about 150 runners and a cake so big it took a UNE mathematician to figure out what size each piece needed to be so there was enough for everyone to get a slice.
It was an event set to commence at 8am on a "very crisp" morning and attended by some out of region runners. Someone from the Gold Coast was heard to comment on the close to zero morning.
"Bloody ridiculous," one of the runners said.
The comment got a laugh from those who heard it.
About 15 volunteers were on hand to run the event and secondary school teacher and mathematician June Billing took on the task of cutting the very large cake.
Tim Dyall and Paul Billings organise Armidale's Parkrun every week and usually have about 150 runners participate.
"It's all run by volunteers and basically available every Saturday morning at 8am at Sport UNE," Tim said.
"In the winter numbers drop back a little bit over some of the colder weekends, but in the warmer months we're probably up closer to 200 people per week."
