i did this event as my first ever half marathon and ran it for the charity Mind. The location of this event is stunning, going through the different parks and past Buckingham Palace and you would never know that 16,000 people were running. The waves started smoothly and there never seemed any issues with too many people at any point. The volunteers were amazing, whilst wrapped up as it was a cool morning, they clapped and cheered us all on all the way around including a lady at mile 12 saying 'don't despair you're almost there!' Fantastic. The mile markers were large and easy to see and with all the scenery to look at the miles ticked off even for my slow legs. With two lucozade stations as well as the 5 water stations there was plenty to keep you fuelled along the way. Great festival zone, awesome medal and amazing route. I will definitely be trying to run it again next year.
