During online registration you will select how you will be taking on the Challenge - and a start time bracket which have been set to ensure your finish (based on your target time) is within the hours of public transport - so you aren't waiting for hours at the night. All Challenges start on Saturday 10 Sept (bar last 25km option, which starts Sunday)
