Thank you again for such a well organised event - my second 100K! However tough the Challenge, I always appreciated the support and facilities you provide and special thanks to all the volunteers for their kindness and encouragement.
A very special thank you the teams behind the organisation, the volunteers on the day, the first aid crew and the massage therapists. I finally made it into Arundel and I could not have done it without the support at each rest stop.
