What is the Fibonacci parkrun challenge?

The Fibonacci parkrun challenge is a maths-themed collection built around event edition numbers. The sequence grows by adding the previous two numbers together, giving targets such as 1, 2, 3, 5, 8, 13, 21, 34, 55, 89 and beyond. A finish at a venue's 55th event counts towards 55; your own number of completed parkruns isn't relevant. It's a fascinating way to look back through a results history, but it has a historical caveat. The 5K app removed Fibonacci from its default challenges in 2023 following concerns about event-number tourism overwhelming volunteer teams.
