I just check the web site & it says there are still entries on the day. I hope that's correct as I plan to enter tomorrow. I think thgistration is from 8:45 at the bandstand (Hyde Park corner tube end)
I know some people have been saying £20 is a lot to run in a park but it's better than slogging-out the miles on your own - no fun at all.
Anyone who wants a more stimulating route could try the Gade Vally Harriers run the same day. I did it last year and it's a well organised run with lots of cake at the end! But it'll be cold & windy on the many hills which is why I'll be heading to Hyde park.
