Is anyone intending to do multiple parkruns? You might be able to get an extra two or more in at Christmas and New year. Christmas they only allow 1 to be registered (why not volunteer for the other?) and new year only two.
There is a website showing how to find out where the multiples are possible
christmas + new year
I've got my two NY runs sorted !
I've done this before and it's great fun a cross between parkrun and treasure hunt
And two parkruns with an hour break is far easier than a straight 10k. Most graduates should be able to do it, and it's good training to reach 10k.
