To calculate your 10 mile estimated race time using your race pace, please use the Pace Calculator.

If you have previously run a different distance to a 10 mile and you think you are at a similar fitness standard to when you did your time for that distance, please use the Runners World Race Time Predictor which is a good guide to converting your previously raced distance to an estimated time for the 10 mile.

If you are still unsure about your estimated time for the Derby 10 Mile race, please input 120 minutes.

There is a cut-off time for all runners of 2hr 30mins to complete the 10 mile distance. That equates to 15 minute per mile or 9 minutes per kilometre or 4 miles per hour pace which is a brisk walking pace.  We will do our best to support anyone to get around the course and we will have a degree of flexibility with this time but anyone much slower than this time may not have the opportunity to cross the finish line and have a time recorded. There will be a sweep vehicle/bike who will record all runners who drop-out or are slower than the cut-off time.

Anyone who falls behind the sweep bike will be considered as out of the race and therefore has the responsibility to proceed following the highway code as a general member of the public.
