I was in the crush that was turned away from the water station at mile 4 where we were told only that we couldn't come into the barracks, that the next water station was in 2 miles (!) and that "more distance would be added at the end" - helpfully without telling us how much.
There were significant bottle necks in the course where the only thing you could do was walk because of the sheer density of people, we had to wait nearly 30 minutes in the pens to start and the music was pretty much non-existent for the vast majority of the course!
I wouldn't recommend this one unless maybe you are out at the front. No fun in the middle for a lot of the race.
I have a lovely little budgie who has more space in the house which she claims as "hers" than I do - currently she has the whole conservatory with toys and perches hung up all over the house and her cage is never closed. She is a happy, healthy bird who loves reggae and (bizarrely) Italian male choral music. As with all things, it is a massive generalisation to say that keeping pet birds is cruel.
