James Baker and Lesley Locks return to defend their Hayling 10 titles on Sunday.
Around 500 runners are expected to be on the start line for the fast, flat 10-mile race hosted by Havant Athletics Club.
They will be hoping for a repeat of last year’s excellent weather on race day.
That would allow Baker and his main rivals to have a crack at beating last year’s winning time of 52min 37sec.
Zack Lahlal, of Havant-based club Victory, finished second, while Richard Murphy, of Denmead Striders, took third spot.
Locks, of Hart Road Runners, saw off the challenge from Victory’s Jackie Lloyd to take the 2014 ladies’ title in 1.02.55.
It is always breezy, but that doesn’t seem to stop fast times on what is arguably the flattest course in the southMalc Lavery
Race director Malc Lavery is looking forward to seeing whether the defending champions can repeat their success.
He said: ‘Lining up again is James Baker and Zack Lahlal, from Victory, who finished second in 2014, only seconds off his personal best.
‘Lesley Locks, from Hart Road Runners, returns to defend her win.
‘It is always breezy, but that doesn’t seem to stop fast times on what is arguably the flattest course in the south.’
The race route has been changed slightly this year because of the work taking place on the Hayling Billy Line.
A long section is still cordoned off, therefore runners will take the usual northerly run along West Lane and then make a sharp turn back down the same road before rejoining the original course at the bottom of the Billy Line.
Lavery added: ‘There will be entries permitted on race day as long as total numbers aren’t exceeded.
‘With more than 500 parking spaces on the seafront next to the funfair and further parking along Seafront Road, there is only a short walk to the Community Centre and the start in Bacon Lane at 10am.
‘Havant Athletic Club would like to thank the volunteers and the residents on Hayling Island for their support.
‘Also thanks to our sponsor Graham Powell, at Sycamore Cars, who has supported the race since it started in 1982.’
