This is a brilliant add-on. As mentioned in one review, it is sometimes affected by changes to the parkrun website and the developers have to play catch up. They are as swift as they can be under the circumstances. I suspect that most folk who can't get their add-on to work have an ID-10-T problem rather than an issue with the extension.

A great extension that enriches the basic parkrun data with additional information and challenges. As the developers aren't part of the parkrun team, sometimes changes to the website cause problems for the extension, but they usually get fixed fairly quickly.

I have Firefox installed on my Android phone solely to use this extension - it's that great. I really enjoy being able to access the stats, badges, and (my favourite) the map of parkruns visited which is always challenging me to fill in a 'hole' or extend the green visited area a bit further.

Fabulous extension, which used to be used by many parkrunners, particularly tourists, but sadly isn't compatible with current Android versions of Firefox (since v. 68.11.0, I think), all because Firefox dropped support for all but a few extensions. I've refused all subsequent Firefox updates since then so that I can continue to use the extension.
Fingers crossed Firefox do the decent thing!

Fantastic addition to all things parkrun

The Running Challenges extension displays a whole host of fun statistics about our parkrun participation , which adds a new dimension to the parkrun experience.

I recommend you find your NENDY by installing the Running Challenges plugin in Firefox and set your home parkrun in the preferences and enjoy some parkrun adventures.

This ad-on is simply amazing.What a way to spice up and claim your parkrun achievements and especially boost the volunteer community and their stats (something parkrun HQ can learn from). Well done.
