This league comprises 14 clubs from North London and Hertfordshire. It should not be confused with the road running Sunday League – also known as the Summer League.
The standard is somewhat lower that the Metropolitan League therefore, it provides less experienced club members with an excellent introduction to cross country running. The league is a team competition. There are 8 "scorers" in the men's "A" team. The next 8 finishers count as a "B" team. The first 5 women score as an "A" team with the next 5 counting towards a "B" team. There are also veteran men's (4 to score) and veteran women's (3 to score) teams. There are no junior races in this league and both first and second claim Serpies can count towards the scoring team.
At the end of the season there are trophies for the winning teams and the leading runners in various age categories.
Women and men both start together, at 10.30am, and run the same distance. Race distances vary between 5 and 6 miles.
