The support and friendliness of the staff and volunteers everywhere has been amazing - obviously all rest stops and walking through the finish line. Also the night-time route signage with the glow sticks was AMAZING!!

I love the level of support from everyone. There’s a great atmosphere and that’s part of why I love doing these challenges. My friend now loves them too!
