This Sunday's Winchester Half Marathon is the biggest in the race's history, with nearly 2,000 people set to take part.
The notoriously gruelling course - which has been described as nine miles up and four miles down - is the city's fourth annual half marathon.
Chris Rees explained the wider significance of the event on the local economy to The Breeze:
"(Local businesses) see a big uplift in trade, we've got all these extra people who come in for the day to come and experience the city centre. It's not just about running.
"It brings in lots of spectators who.have coffees and go shopping whilst their other halves are out running.
"It's just a really nice family-friendly day. It brings the Winchester spirit alive.
"Come down and come join. Be part of it, Winchester is very much open for the day."

Other significant runs in the area include The Winchester 10K, Parkrun and the Clarendon Marathon. The Race Director - Chris Rees - also said:
"The Winchester Half Marathon fits beautifully into the calendar for the city.
"It's a really unique event because it is a city-centre start and finish. There's some beautiful historic parts of the city that people run past - including going past the Cathedral which is a fantastic backdrop for all the runners.
"You head out into the beautiful Hampshire hills, it's got some lovely spectator support on route ... just seems to attract a good fun group of runners who enjoy the event.
"It should be one that runners do as part of a tick-list for the Hampshire area."
