RACE 01 · CASTLEFORD 10K
Off to a flying start
42 championship members completed our opening event, including one guide runner. Well done to everyone who ran, and thank you to our supporters.
41 scored results · 1 guide score pending
Race 1 results. Complete three events to qualify for the final championship standings.
Underlined scores count towards the best-three total. A dash means the runner did not complete that race.
How the championship works
You run the races. We calculate the scores.
You don’t have to be the fastest to win
You’re racing against your own expected performance. We compare your race time with your predicted time, so runners of different speeds can compete against each other.
Everyone starts and races normally. No head starts — the handicap is used afterwards to work out the results.
Run at least three races
Choose from the six championship events and enter each race separately. You can run all six, but only your best three scores count.
Compare your time with your prediction
Your starting handicap is an expected 10K time. We convert it into a predicted time for each championship race, then compare that prediction with your official finish time.
- 100% — exactly as predicted.
- Over 100% — faster than predicted.
- Under 100% — slower than predicted.
The higher your percentage, the better your performance against your prediction. You don’t need to calculate anything yourself.
Your percentage earns your place
We rank championship runners from the highest performance percentage to the lowest, then award race points:
1st100 points2nd99 points3rd98 points
Points decrease by one for each place. Your percentage is not your points total. It decides your championship place, which decides your points.
You still earn points if you run slower than predicted. These are championship places, not full-race finishing positions.
Your best three scores count
We add your three highest race-point scores to give your championship total. The highest total wins.
For example: 90 + 85 + 80 = 255 championship points.
Why two minutes isn’t always the same
Both of these runners beat their prediction by exactly two minutes. Do they get the same score? No — because two minutes is a bigger proportion of 45 minutes than of 60 minutes.
Made-up examples, not members’ personal times.
| 10K example | Runner A | Runner B |
|---|---|---|
| Predicted time | 45:00 | 60:00 |
| Actual time | 43:00 | 58:00 |
| Time saved | 2 minutes | 2 minutes |
| Performance score | 104.65% | 103.45% |
Runner A places higher in the handicap results. Both saved the same time, but Runner A performed better in proportion to their prediction.
It’s not simply how many minutes you save — it’s how well you perform relative to your own predicted time.
Want a little more detail?
Can a slower runner still beat a faster runner?
Yes. Imagine Runner A is predicted 45:00 and runs 44:00: their score is 102.27%. Runner B is predicted 60:00 and runs 58:30: their score is 102.56%.
Runner B finishes later but earns the higher championship place, because they performed slightly better against their own prediction.
How is my predicted time set?
Before the first race, each runner gets a realistic 10K-equivalent handicap based on recent race results, parkruns and other relevant evidence, including current fitness and time away from running.
We use that starting time to predict each race distance, applying the same distance-conversion method to everyone. Any agreed course adjustment is also applied consistently across the field. You don’t submit a new prediction before each race.
What is the actual calculation?
Performance % = predicted time ÷ actual time × 100.
For Runner A above: 45 ÷ 43 × 100 = 104.65%. For Runner B: 60 ÷ 58 × 100 = 103.45%. Use the same units for both times; the spreadsheet uses seconds.
A score of 104.65% is a performance score, not a claim that the runner cut their predicted time by exactly 4.65%.
For other distances: predicted time = 10K handicap × (race distance in km ÷ 10)1.06, followed by any agreed course adjustment. This allows for the fact that runners cannot usually hold their 5K pace over a longer race.
The spreadsheet handles all of this automatically.
Will my handicap change?
Starting handicaps normally stay fixed for the six-month trial. They are only revisited for a clear error or an exceptional change in circumstances.
Why is a guide runner’s score pending?
A guide run can count as one of the three qualifying events. If the guide completes two other championship races without guiding, the protected score is the average of those two race-point scores: for example, 70 and 80 give 75.
This allowance can be used once during the trial and is finalised after the last event. If the guide completes three or more races without guiding, their best three normal scores count instead.
We match official results to registered championship members and check the scores before publishing. Chip times are used, except at parkrun where the published finish time is used. Individual handicaps and predicted times are not published on this site.
Good to know
Do I need to enter all six races?
No. Complete at least three to qualify for the championship. If you run more, only your best three scores count.
How does guiding count towards the championship?
If you act as a guide for a visually impaired runner at a championship event, that event can count towards your three qualifying races. Please let the championship organiser know.
If you complete two other championship races without guiding, your guiding event receives a protected score equal to the average of those two race-point scores. For example, scores of 70 and 80 give a protected score of 75.
This allowance can be used once during the trial and is finalised after the last event. If you complete three or more races without guiding, your best three normal scores count instead.
Will my handicap change during the trial?
Handicaps stay fixed so everyone competes on a consistent basis. They would only be revisited for a clear error or an exceptional change in circumstances.
Which race time is used?
Chip time is used for timed races. The nominated Temple Newsam parkrun is the exception.
Do I need club kit?
Please wear official club kit where available. Runners without kit are still welcome and should let the organiser know.
Does registering for the championship enter me into each race?
No. Championship registration and race entry are separate. Each runner is responsible for entering the individual events they want to run.
