If you complete any of the relevant races you will automatically be included in the club championships. There are 18 races in total, six short, six medium and six long, and to count in the final standings you just need to complete ANY six races. There is no requirement to do one from each distance so you could just do all six short races, for example.
The first Pennine runner in the race gets 100 points, the next 99 and so on. Therefore, if there aren't many Pennine people at a particular race, you can get lots of points even if you're right at the back of the field.

There's an open championship and a women's championship with prizes for the top three finishers in each. Use the select box to find the women's results, grand slam results, etc.

There are also male and female Vets prize, although people can double up so if the top three overall includes a Vet, they will also get the relevant Vet award. You only get the Vet award for your age category though, so if the first Vet is a V50, they don't get the V40 prize as well.
