Irene Speller has pleaded with her Windsor, Slough, Eton & Hounslow champions-elect female athletes to turn up and finish the job next month.
WSEH top the Southern Womens League Premier Division with just one match remaining after their fourth win in four fixtures on Saturday.
However, despite that fine unbeaten record, they are still just 17.5 points ahead of Reading and 23 ahead of Herts Phoenix, so there is still all to play for.
But team manager Speller fears it could all count for nothing if her top athletes fail to commit to the long trip to Newquay for the final fixture on August 30.
She sid: "It would be a real shame if we missed out on being league champions if insufficient athletes make the trip to Newquay."
There were personal bests (pbs) for both Ana Gomez and Emma Croft in the girls sprints, for Zoe Wells in the senior 200m and for Georgina Wilder-Connor in both senior sprints.
Caroline Livinsgtone bagged her second successive sub-60 second 400m, while Michelle Warren ran a superb 65.8 mins in her first race back after a lay-off of several years.
More pbs fell in the distance races for Rosie Adams and Jo-Ling Chew, while former Commonwealth champion Paula Fudge used all her experience to win the 3,000m. Fudge used her ability to cope with the energy-sapping conditions to great effect, while Leigh James made it a WSEH 1-2 in the B race.
In the field, Hannah Kirby recorded a pb after stepping in to cover the 80m hurdles, while Sarah Taplin and Jenna Grant landed double victories and pbs galore in the shot and javelin.
Jo Botwright, Jo Wade, Bola Ogun and Laura McGawn chalked up victories in the senior throws. McGawn and Georgia Taylor dominated the senior high jump, while Demi Barrance and Pascale Waterson gained pbs in the girls jumps.
The Gomez twins, Ana and Maria, dominated the girls long jump, while the senior women crowned a fine day by winning both relays.
Meanwhile, WSEH's joint U20 mens and womens team are on course for qualifying for National Junior League Finals for the fourth year in a row after finishing fourth in their regional division.
Nigel Levine was back in action for WSEH following his silver medal for Great Britain in the 4x400m relay at the World Junior Championships.
But the undoubted highlight was a double win in the 3,000m for Nathan White, running his second 3,000m of the weekend having raced in the Crystal Palace Grand Prix, and Lewis Sloan, making his Junior League debut in the distance.
Jamie East achieved no less than three pbs, while Rhys Glastonbury, having run a pb in the 800m, filled in for the 1500m B race too and won convincingly.
Further pbs came on the track for Elliott Woolmer, Nathan Ditton and Cameron Smart, and in the field for Blake Crowe and Moritz Holbrock.
The women shone too, with Sarah Spears and Letisha Richardson scooping pbs on their debuts to add to those recorded by Martha Reynolds, Helen Farmer and Shelayna Oskan.
Oskan's saw her break the club record in the 400m, and another WSEH record fell in the 4x400m relay, thanks to Richardson, Becky Richards, Jenny Heckford and Chinedu Monye.
Team director Bryan Goodman said: "Coming fourth in the league is a great achievement considering how reliant we have been on out U17 athletes. The dedication and commitment shown by the two team managers, Paul Fudge and Lesley Tovey, is worth a 10-point start."
