Challenges

As a means of keeping runners engaged with parkrun, participants (and in some cases parkrun themselves) have drempt up a wide range of challenges. Some of the challenges are passive, such as All Weather Runner (tracked by the Running Challenges browser plugin), while others require more active engagement.

This page summarises the challenges that I am actively engaged with. My progress is highlighted, and is correct as at 14 May 2022.

Wilson index

This challenge is simply to have the highest index based on the length of the unbroken sequence of event numbers run at, starting at 1.

For brevity, I will only track the first 50 events until I make more progress.

Fibonacci sequence

This challenge is based entirely on the number of times an event has been run, and to participate, one simply needs to run an event whose event number corrolates to a number in the Fibonacci sequence.

As the Fibonacci sequence is infinite, it's technically not possible to complete this challenge, but given an event only typically runs once per week, there is likely to be a gap of over 11 years between the first event reaching 987, and that same event reaching 1597 events, and a further 19 years until that same event reaches the next number in the sequence. Bushy is currently likely to be the first event to reach 987 events, and like not before 2024.

I initially started my Fibonacci journey manually checking event numbers, however, I soon found Keith Bennett's Event Number Predictor spreadsheet, which became an invaluable tool when it came to planning specific events.

Alphabet

The alphabet challenge is what introduced me to parkrun! Simply run at an event whose name starts with every letter of the alphabet!

There are currently no parkrun events around the world whose name begins with an "X", and all of the events whose name begins with a "Z" are outside the UK, and so I've paused my progress towards this challenge at completion of the UK alphabet.

Pirate

One of the challenges first popularised by parkrun was The Pirates Club. The challenge is simply to run 7 events starting with a "C", and another starting with an "R".

I haven't actively focussed on attaining this challenge, instead preferring to let the events accumulate naturally, and I finally completed the challenge at Chilton Fields parkrun on 22 October 2022.

The events I attended to complete the challenge were:

Snakes

As a number of parkrun challenge apps and websites became more prominant, they each introduced a number of challenges to cater to their audiences. Snakes is one of the challenges introduced by the Running Achievements app. The challenge is simply to run 10 events whose name starts with an "S".

As with the Pirate challenge, I haven't actively focussed on attaining this challenge, instead preferring to let the events accumulate naturally, and I finally completed the challenge at Swaffham parkrun on 03 September 2022.

The events I attended to complete the challenge were:

Ally Pally parkrun

Now that I have completed the UK Alphabet, my focus has turned towards the East of England region. As there are so many events to choose from, I'm going to start by working through events in alphabetical order again, with an emphasis on working east to west, which for me, effectively orders events furthest to nearest. During my initial exploration of the challenge, I did make a mistake however, which I only realised after running this event - I didn't realise that Aldenham parkrun was in the region, and so I started this phase of parkrunning by running Ally Pally parkrun instead! The area Ally Pally, or Alexandra Palace, is a purpose built community centre in Haringey, North London. Unlike other palaces in the UK, Ally Pally has no royal connection, and instead has been entirely community oriented since its conception. The palace houses a theatre, concert hall, a convention centre, an ice rink, and has facilitated BBC broadcasts an

York parkrun

After the exciting return of parkrun last week, I was super keen to complete my outstanding alphabet challenge without as many hiccups as possible, which meant ticking off the rarer letters while I still had the possibility to divert to other events as possible. Yeovil Montecute parkrun hadn't returned since the break, leaving York as the only option for a "Y", and so while I still had some contingencies available in the forms of Wetherby and Potternewton parkruns. While not a big factor in deciding this week's destination, this was to be York's first event back, as it wasn't able to take place last week due to horse racing taking place. The area York parkrun takes place in the Knavesmire, in the south of York. The city of York was founded in 71AD, and then known as Eboracum, was the capital of Britannia Inferior - one of the Roman provinces. As with any city of this age, its history is vast, and the city has played many imp

Alton Water parkrun

While I have been looking forwards to attending Alton Water parkrun for a while (it shared its inaugural run with Bury Field, which I attended), the fact that attending this week also gives me some more progress towards the Fibonacci sequence by ticking off a 13th event was enough to tip the scales in its favour this week. The area Alton Water is a reservoir, built to provide drinking water to the Ipswich area following water shortages in the 1960s by building a dam at the eastern end of the lowland, and allowing water levels to rise over the course of the next 10 years. The area which was claimed by the reservoir, as well as today's surroundings are primarily farmland, punctuated by the occasional village. The course The two-lap trail course is run primarily on grass, with some gravel and dirt paths for good measure. The course is situated to the south of the reservoir, and offers views of the water, woodlands, and farmland, while cattle, geese and waterfowl are commo
