They begin with a bang, owing to the traditional firing of a cannon, and end with a bang in a similar way.
And sandwiched in between is an explosion of athletics.
Jedburgh Border Games is the occasion and this historical event is set to take place at Riverside Park on Saturday, beginning at noon.
Big prize money is up for grabs in a variety of youth and senior races.
Main event on the card is the Jed-Forest Sprint 110 metres handicap, which has a winning prize of £3000.
The sprint consists of nine heats and back marker for the event is Berwick flyer Cameron Tindle.
Representing TLJT, the classy Tindle, a former winner of the handicap, has been placed on a mark of minus two metres by handicapper Don Campbell.
Cameron’s younger brother, Scott Tindle, a recent beaten finalist in the City of Edinburgh Running sprint, runs from 10 metres.
Bidding to put himself into the record books is Jedburgh’s own Scott Elliot.
Coached by Brian ‘Chico’ Woods, Elliot has won the prestigious race twice in the past.
Nobody, as yet, has managed it on three occasions, but this will be Elliot’s aim.
Another big home hope is Sophie Elder (21m) who, on last week’s showing at the CERF meeting, when she came in second in the final, must be in with a chance.
Terry Marshall (9m), Brodie Cowan (22.5m), Craig Gillan (7m), Cameron Clamp (9m) and Oskan Barskanmay (8.5m) also go for the Burgh town.
The race is a wide open affair, though, as last year’s sprint proved when Hawick veteran Drew Bryson emerged a surprise winner.
Bryson runs from 25 metres on Saturday.
On a long list of Border athletes due in action are Mhairi Henderson (27m), Eilidh Murray (22.5m), Nina Cessford (27m), Emily Dagg (17.5m), plus James Parker (5.5m), Ryan Elliot (8m), David McKay (17m), John Fleming (11.5m), Cameron Caldwell (5m), Angus Johnstone (13.5m), James Park (14m) and Colin Bruce (15m).
Kelso’s Douglas Young is listed as being off six metres but this mark will be changed, after he won the CERF sprint handicap.
Besides the sprint, there is a full programme of senior and youths racing, with prizes of £100 and over to be won in the youth events.
