Re: Tube Challenge parkrun league...

So Sweden has extra parkruns on its National Day

In the UK we have extra parkruns on our bank holidays Christmas Day and New Year's Day.

Do other countries do similar? How many worldwide parkruns could you complete in a year?

Re: Tube Challenge parkrun league...

I'm aiming to start the new year at Whiteley with my first parkrun in what seems like forever (but was actually 7 April).

Re: Random 15 Championship 2018/19: Round 2

So, I hope your royal tangyness will make sure the following stations are removed from the random generator for envelope 2, as I understand it they won't have any NR service on Saturday, according to the works listed on page 1.

Re: All the terminals

There was a challenge to do all Zone 1 NR stations a few years ago. It was a really fun challenge. Results here: http://www.tubechallenge.com/forum/viewtopic.php?f=4&t=2852&start=120#p79208 I don't think it meets your precise definition, but it's similar.
