Who will be the 250,000th new parkrunner?

As of last weekend (Saturday 8th Decmber 2012), 248,958 different people have run and completed a parkrun somewhere in the world.

The current trend is for roughly 1600 to 1800 new runners to run their first parkrun event each weekend. If this trend continues we should see the 250,000th new parkrunner complete their first parkrun this coming weekend!

So who will be parkrunner 250,000? And more importantly, will they be dressed as a Santa or an Elf?
