Episode 456 - The hype team
Sung (unaccompanied, with running gags about the non-existent budget). St Helena's Plantation Forest parkrun had 50 finishers on 1 August (9 unknowns, 8 first-ever parkrunners) and 35 finishers on 8 August (7 unknowns, 2 first-ever, 9 volunteers). Lyndell notes unknown numbers falling as locals register, first timers returning, and several first timers who last ran parkrun in 2017-18 - possibly parkrunners who have moved to the island.
