The English National Cross Country Relays return to Berry Hill Park on Saturday, October 31. This year marks the 40th edition of the event, first held in 1985. Tonbridge and Belgrave Harriers are the defending champions.

The relays feature a new mixed 4x1600m event, with teams of two men and two women. Age groups have been renamed, with U14 and U16 replacing U13 and U15. The course has minor changes due to development work. Read more racing coverage.
