The nerves are setting in for almost 15,000 runners preparing to tackle the Bath Half Marathon on Sunday.
Thousands of spectators are expected to turn out to support runners as they make their way around the 13.1 mile course.
The race continues to be popular with experienced runners who return year after year, as well as attracting many first-time athletes.
It begins at 11am, and starts and finishes at Great Pulteney Street.
Road closures and parking restrictions will be in place during the event, with extra disruption due to the closure of the A431 at Kelston.
Anyone heading for Bath this weekend could face significant diversions.
The closure of the A431 Kelston Road and road closures associated with the Bath Half Marathon mean people travelling from Bristol will have to take a detour along the A420 through Wick and the A4174 the Avon Ring Road.
Between 9.45am and 3.30pm on Sunday, Newbridge Road, Lower Bristol Road and Upper Bristol Road will be closed because they are part of the race route.
