Hi, my name is Jess and I will be completing a Ultra running challenge on Saturday 23rd August. This is a challenge ran by my gym JJK to raise money for Parkinson's UK.

The rules:

9am start on Saturday 23rd until 9am Sunday 24th August.

Run 1 loop every hour, starting on the hour, for up to 24hr. Each loop is 4.167 miles (6.706 km) around Kings Langley.
