Once a month, a handicap race is held from Sevenoaks School Track, over 5 or 7 miles in Knole Park. It is normally held on a Sunday Morning at 9:00.
Handicap is based on the runner's best time in the last 12 months whether over the 5 mile or 7 mile course. To see how your times convert between the two courses, click this link.
A database of handicap performances going back to May 1988 is here. It includes every result on the two current courses (Phillips 5 and Dillon 7). (NB. the fewer the selections made, the more data is retrieved.)
