City of Portsmouth athletes dominated the opening round of the Chichester Corporate Challenge road race series.
The City girls won the years seven to 10 age groups and made up three quarters of the 20 top secondary school finishers.
Saffron Moore came first in the year-seven category in a time of 7min 22sec.
Club-mate Charlotte Bullard was second in 7.52.
Olivia Wiseman topped the year-eight category after clocking a time of 7.10, and Bo Sansom followed in a time of 7.43.
In the year-nine category, Anya Pigden’s time of 7.21 earned her first place.
One of the closest tussles of the night was between team-mates Maisie Grice and Elizabeth Rose in the year 10 age group.
The pair were neck-and-neck throughout but Grice just pipped her to the win by a second, finishing in 7.01.
City coach vince Stamp said: ‘Maisie caught Libby (Elizabeth) on the line – she was only ever 30 or 40 metres behind. Libby was in front with 100m to go but Maisie’s got a very fast sprint finish.’
City’s boys made up four of the top six places among the year eights.
Callum Crook (6.51) came second to Ethan Fincham, with Josh Goldfinch (7.02), Ben Czura (7.18) and Thomas Haskell (7.22) making up the rest of the places.
Similarly, Jacob O’Hara (8.45), Adam Kimber (9.12) and Harry Moore (9.20) finished second, third and fourth respectively in the year nine age group.
Ted Yeates was the clear winner in the year 10s with a time of 9.11.
Stamp added: ‘We always support Phil Baker’s run.
‘The youngsters really enjoyed the event.
‘They do it for a bit of fun because they’ve worked hard all winter. It gives them a different experience.
‘It’s a nice race around the city centre, it’s traffic-free and there’s a really good atmosphere there.’
The challenge is a three-race series, with the next event on Wednesday.
