What you’ll need
Bring some running gear, a watch and a pen or pencil to fill in the cluesheet. You might also wish to bring a headtorch and hi-visibility clothing.
You can hire a timing chip if you do not have your own.
How it works
You have an hour to find the clues indicated on the map and get as many points as you can. The clues are worth different points, and so tactics are involved in deciding where to go. If you’re over an hour, you lose points – so don’t be late. The penalty is 1 penalty point for every 2 seconds late back (so you’ll lose 30 points if you are a minute late back etc.). This guide provides more information about street orienteering.
Series points are scored at each event, with 100 for the winner, 99 for 2nd place, 98 for 3rd, down to 1 point for everyone who finishes 100th place or lower. The event score is based on the net score (gross score minus time penalty) and equal net scores are ranked on time (shorter time gets higher event score). The organiser of the event scores points equal their best at any other race in the season. Men and women are included in the same combined results table for each race, and overall, but women’s positions will be highlighted in the results.
The overall results will be based on your best 5 scores in the series, and there will be prizes for the leading man and leading woman over the series. In the event of a series score tie, the most recent head-to-head result will be used.
