Please find below full details of our 50 and 100 mile Grand Slams including how to enter, which events are included and all of the current and historical results.

Grand Slam awards recognise those who complete all four Centurion 100 mile or all four Centurion 50 mile events within a calendar year.

GRAND SLAM ENTRY

Entry to the Grand Slam is automatic for anyone who enters each of the 50 or 100 mile races individually.

But the Grand Slam can also be entered as a whole. There is no additional benefit to entering all four races at once, other than that it saves entering each one individually.

The refund policy remains the same as entering each event individually. Four weeks up to race day you can receive a 70% refund on the race entry fee for that individual event or events, if you choose to withdraw from more than one at the same time.
