first time at Royal Parks for me and was really looking forward to it. I was supposed to be in the green pen (I missed my wave due to the toilet queues and ended up in blue wave which was HUGE!), so ended up playing dodge the runner / walker for at least 4 miles. Really lovely run, good course, lots of going back on yourself and corners, so be prepared and check the route in advance. LOADS of water stations though, more than I've seen at any other race so plus points for that. Loads of volunteers to guide you round the course, esp Zig zagging round Hyde park. You get to run through Admiralty arch twice, past the palace twice (I did wave to Liz but she didn't wave back). The charity support support point just before 10k was amazing! All the charities lined up cheering everyone on. Plenty of pacers on the course too. A sustainable race too. The tshirt was made of recyclable material and the medal made from a tree from one of the parks on the course, which is lovely. I'm still waiting for my official finish time, 7 hours after I finished though. Great atmosphere, lovely views and landmarks to run past, hundreds of supporters, just add more toilets next one please! Update.... I may not have had my chip time asap after the race but the email I received the day after was brilliant. Great set of stats about the race / participants, age, gender etc
