James Baker will be looking to defend his crown as the City of Portsmouth 5k series starts next week.
The Chichester runner is expected to face tough competition from exciting Portsmouth youngster Harry Carter.
Baker has dominated this event in recent times, winning three of the five races last year.
But 20-year-old City of Portsmouth talent, Carter, has come out on top in their past three meetings.
Defending women’s champion Cassie Thorp is working her way back to fitness after injury.
She will have her work cut out to challenge the course record of 15mins 45secs, set by Olympic hopeful Jo Pavey who was a surprise entrant last year.
The five-race series, organised jointly with Havant Athletic Club, has switched venues this year.
It will take place in The Lakeside North Harbour Complex, with Hilsea Lido the registration point.
The first race of the series is on Wednesday, starting at 7.15pm.
Race director Peter Newton said: ‘It is great to be working with two local organisations for the benefit of sport.’
Karen Tyrrell, sales and marketing manager at 1000 Lakeside, added: ‘We are delighted that the City of Portsmouth Athletic Club is making good use of our superb grounds.’
Hilsea Lido Trust hope the race is a step forward in hosting sporting events.
‘We hope that in the future we will provide other sporting and leisure activities at Hilsea Lido besides wake boarding, scuba diving and kayaking, which we already host,’ said Sabrina Richards, chair of the Trust.
‘We also feel Hilsea Lido is ideally suited for the provision of mini triathlons and hosting this series of races is an exciting step forward.’
