In mitigation for the organisers of the format, there is no easy way to do it with 10 riders. The ideal numbers are 8 or 16. So, either you tell two of them they can't race or you find 6 more. The problem with the latter is that to boost it to 16 you could be putting riders in who are not ready.
Not an ideal format, but just to see the lads performing was great.
Also, no riders were 16 as I had a copy of the sheet giving all the dates of birth. Youngest was 11 and oldest 15.
