The Dave Ashdown Memorial Time Trial is a 10-mile cycling time trial on a flat course in Medway, organised by Cycle Club Bexley under Cycling Time Trials rules. It takes place on the Q10/24 course at Grain, with an afternoon start, and has a rider limit of 120. The event also incorporates the Tricycle Association South Eastern Region 10-mile competition, meaning it is not solely a solo time trial field.
Riders begin on the A228 west of Grain Village, proceeding west to the Fenn Corner roundabout. They turn just past the five-mile mark and return on the same road, finishing close to the start. Stoke Village Hall in Lower Stoke is the event headquarters. Awards are presented for open, female, veterans, junior or youth, team-of-three, and road bike categories. The number of prizes awarded in each category is determined by the number of entrants. The race honours Dave Ashdown as a memorial event, with Richard Boxall serving as the Cycle Club Bexley organiser and secretary.
