We were so impressed how well organised it was. From registration to the finish line everything was amazing - the staff were so lovely and helpful - the catering was outstanding and all the facilities clean and tidy. A huge thank you to you all!!
Such a good feeling crossing that finish line after 100km of walking. I must say a special thanks to the guy doing the massages at the 78km stop at around 5.30am. I may not have made it without his healing hands! Great event, well organised and would recommend that experience to anyone!
