I cannot thank everyone enough for their personal support and unlimited energy. 5★★★★★ and 10/10 in all my experiences.

For my first event, I was amazed at how well-organised it was. Particularly as I was on my own. Very well signposted. Excellent medical assistance. Very friendly crew. Fab event!
