The youngster strode out to a significant personal best of 24.84sec. in the headline performance of Aztec Track and Field Series Two, cashing in on the maximum allowable tailwind.
Her time not only stands as a record for her U16 age group but also the U18s and U20s, with only Guernsey sprint queen Abi Galpin having gone quicker.
This Island Games A standard made her an unrivalled winner in a strong field of emerging talent, where U18 Joselyn Ford (26.24), new sprinting convert Kylie Vaudin (26.47) and U18 Olivia Whitmore (26.75) put down B qualifying marks.
‘I feel really happy with it,’ the record-breaking winner said.
‘I’m really proud of what I’ve done. I was not expecting it this early in the season.’
Van Heerden is hopeful of competing at the Faroe Islands 2027, and also has her sights on the English Schools, but more imminently she will be running the 200m and 300m at this weekend’s Hampshire Championships.
Her goals include the clean sweep of PBs this year, even bettering last year’s breakthrough 12.27 for 100m.
‘I’ve not got a PB yet for the 100 this year, so I would like to do that,’ she added.
‘Hopefully I can get a PB for 300, under 41sec., and I’ve just got a PB over 200 but hopefully I can beat that at some point.’
Sunday’s bustling meet crammed in nine different senior events and all four seasons, with conditions ranging from mild to uncomfortably hot – just in time for the series’ only 5,000m – and a late downpour.
The other track highlight was the 800m, where the Friedrich boys recorded times that top their respective national age-group rankings and Eloise Scholes flew all the way to fourth on Guernsey’s all-time women’s list.
U16 Emil Friedrich produced a bold front run to win the senior-level event in a PB of 1-55.24.
Behind him, U18 Tom Holt ran his own PB of 2-05.84 as Paul Friedrich, an U14, posted an eyebrow-raising 2-07.84.
But by adult standards, the most significant performance came from Scholes, who continued her improvement ramp with a 2-10.51 – an 8sec. PB – to close significantly on the times set by the event’s top specialists in the island.
The second heat included U16 Grace King running a Games B standard of 2-18.98.
In the 100m, Daniel Pike posted 11.34 for a Games B standard and overall victory.
Ford followed him home in another PB of 12.79, finishing 0.17sec. clear of reigning Games sprint-hurdles champion Rhiannon Dowinton.
In beaming May sunshine for the mid-day 5,000m race, veteran-45 Matt Jamieson reaped the rewards of a hard, solo effort with a track PB of 16-22.32.
As fellow veteran Peter Amy claimed a distant second in 17-36.85, eyes were on Guernsey 2023 women’s bronze medallist Nix Dobson and her isolated run chasing a Games standard.
She slipped off pace for the A standard but persevered to hit the B mark with 18-34.89.
The hunt for distance standards continued with potential Games debutants George Mason and Mikey Ingrouille taking the rare opportunity of slogging out a 3,000m steeplechase.
Mason ground his way to a time just outside the A standard, 10-05.00, as Ingrouille debuted with a 10-43.50.
In the junior 1,500m ‘chase’, U18 James Stafford-Bell claimed the overall win in 4-48.85 as U20 Eleanor Jamieson took women’s honours in 5-17.87. Jamieson’s time also stood as a Guernsey age-group record.
The hard graft over barriers continued with Nic Ackermann battling solo to an apparent PB and B standard over the 400m hurdles, where he had won an inspiring Games gold after squeezing into the team last summer.
But the catch was that there had been an error in hurdle placement – with the jump approaching the 200m mark missed through no fault of his own – and so his 56.40 clocking could not count. It could instead be taken as an encouraging marker for the season ahead.
On the field, new face and U18 David Bown raised the bar in the high jump with a Games B standard of 1.82m.
Fellow U18 Nikola Vagule won the women’s event and came up just short of a Games standard with 1.50m.
Vagule doubled up in winning the shot put, producing a promising 10.30m with the junior-level 3kg implement.
A duel over the triple jump ended up running quite close, with U16 Finley Nicolle’s 10.16m effort getting him the edge over Games woman Holly Drake’s 9.87m.
