I think mapping parkrun routes is a good thing. They take place
regularly almost every Saturday morning and are certainly verifiable
on the ground during those times. Most routes are the same each week,
though some events have an alternative version for the winter, or to
avoid flooding or other events in the park.

Parkrun's own website has route maps drawn over Google Aerial Maps,
which (from experience) aren't always very good. The routes can be
inaccurate and it's not always easy to see paths on the ground in the
imagery. It's also not always easy to see the direction and
progression of multi-lap routes. It would be great if we could get
better coverage and then persuade parkrun to use a rendering based on
OSM. I think the difficult thing to do would be to off-set parts of
the route that are covered more than once (like you do on bus route
maps when more than one route follows the same road), so the entire
route can be traced. Does anyone know if there are any libraries or
leaflet extensions that do this already?

Robert.

PS: Full disclosure: I'm a run director at Thetford parkrun, and have
mapped a number of events I've run in OSM. e.g.
