# Race classes

Choose between competition classes or open classes The most important differences are

Competition | Open | |

Registration possible after the last post-registration deadline in Eventor? | No | Yes (1) |

More expensive to sign up after the regular deadline? | Yes | No |

Overall ranking (from 11 years old) | Yes | No |

Suitable for exercisers | Yes | Yes (2) |

2) Even though they are called competition classes, 90% of the participants can be considered exercisers

The degree of difficulty in the table below are described in this table from the NOF (Norwegian Orienteering Federation). The numbers indicate age, based on the year you were born. If you are a girl born in 2013, you will be considered 10 years old in 2023 and can therefore run in one of the classes D 9-10, N2-open 9-16, C-open 10-16, B-open 10-16 or N1-open (no age limit).

Difficulty | Competition- Women | Competition – Men | Open |

Green N1-course | N1-open | ||

Green N2-course | W 9-10, | M 9-10, | N2-open 9-16, N2-open 17-, |

Blue C-course | W 11-12, | M 11-12, | C-open 10-16, C-open 17-, |

Red B-course | W 13-14, | M 13-14, | B-open 10-16, B-open 17-, |

Black A-course | W 15-16, W 17-20, W 21-, W 35-, W 40-, W 45-, W 50-, W 55-, W 60-, W 65-, W 70-, W 75-, W 80-, W 85-, | M 15-16, M 17-20, M 21-, M 35-, M 40-, M 45-, M 50-, M 55-, M 60-, M 65-, M 70-, M 75-, M 80-, M 85- | AK-open, AM-open, AL-open (1) |

We have chosen to merge the youth classes as follows: W13-14, W15-16, M13-14 and M15-16. This is to get more participants in each of the classes. We have focused on creating courses with the right difficulty and length for the classes.

Other competition classes will be roughly the same as in 2022, but we reserve the right to merge 5-year classes with few participants into a 10-year class.

# Points per race

- The winner in each race gets 1000 points
- Other runners get 9 point reduction for each percent they are behind the winning time. If the winner uses 10 minutes and you are 1 minute behind, you are 10 % behind the winner and will get: 1000 – 10*9 = 910 points for that race.
- Runners who do not get a valid result gets 0 points.

The youth classes do not collect points the last day (when there is a chasing start).

# Overall ranking

SG2023 wants to make sure you can measure yourself against those that are roughly the same level as yourself. We know it can be difficult to participate all days, therefore we have decided that 3 / 4 races count in the overall ranking.

The rules are as follows:

- There is no overall ranking in the open classes.
- Overall ranking is used for those 13 years and older.
- The overall ranking will be updated after each race.
- The overall ranking sums the points from the 3 best races.
- For the youth classes the overall ranking before day 4 decides the start list for the chasing start on day 4. The order at the finish on day 4 decides the overall ranking in these classes.

# Chasing start for the youth classes

We organise chasing start for the classes W/M13-14 og W/M15-16 the last day.

*The other classes has plain individual start the last day, not chasing start. *

## Equalising measures

The 2 best races decides the starting order on the 4th day.

When it is possible to eliminate the worst result from the first 3 days, the total difference between runnders will be reduced.

Some might argue that this is not fair, but we claim it is a fair adjustment to ensure the differences are not too large. This also means more runners will be starting before the mass start.

## Start times for chasing start

For each runner, we sum the 2 races with the highest score from day 1, 2 and 3: *sum_points_runner*

We denote the sum of points for the overall leader: *sum_points_leader*

Calculate how many points the runner is behind the overall leader:

–sum_points_leader=sum_points_runnerdifferance_points_runner

Starting time in seconds behind the overall leader will be:

differance_points_runner / 9 * 15 = seconds behind leader

Number 9: how many points are withdrawn per percent the runner is behind the winning time.

Number 15: seconds per % behind winner, given a winning time of 25 minutes, which is the estimated winning time in the chasing start.

We convert points to seconds, which are stretched to fit the expected race time the last day. This means that each day has roughly the same impact on the final result, regardless if it is a sprint or long distance.

### Example
