The individual Island Games medallist won the senior 800m title in the Southern Indoor Championships at Lee Valley, making him the shining star among the five Sarnians competing there at either adult or U20 level.
Ultimately Robilliard, whose best previous result at the competition was U20 bronze four years ago, was not even run close in the final.
After winning his qualifying round in the third-quickest time overall, he broke in second after the opening 200m circuit and made an assertive overtake another lap later.
Having gapped the field without hesitation, he pressed home his advantage to win in 1min. 54.98sec. That put him 1.99sec. ahead of silver medallist Harry Wilson as initial leader Gerard McGrady slipped to third.
‘So pleased to win my first senior Southern title,’ Robilliard said.
‘I’ve done this competition quite a few times and have taken bronze once at best so nice to finally get a gold.
‘Indoors are always a good marker to lay down in preparation for the summer, so I was pleased to run some well-executed races.
‘One of the other guys took it out hard for the first 300m or so and I just stayed relaxed and didn’t panic, trusted myself to have the ability to turn it on with 400 to 500m to go, which I did, and felt smooth the whole way.
‘It’s nice because it shows that the more races you do, the more experience you do get for sure.’
Robilliard, who dipped under 1-52 last summer, certainly has much to look up to this summer season.
‘I’ve had a better winter this year than last year, so hopefully that’ll work in my favour heading towards the summer as well as I eye up a few BMCs and the England national champs in July.’
Meanwhile, Abi Galpin secured not one but two silver medals following an interrupted outdoor season.
The Commonwealth Games athlete started off with Saturday’s long jump, where she covered 5.62m for a firm second behind Harrow’s dominant Alice Hopkins.
The following day’s 200m final proved a much closer affair and she ran 24.68, one of her quickest indoor times to date, to finish just 0.06sec. short of Belgrave’s Sian Harry.
This had taken place less than 2hrs after a similarly quick semi-final, which she won, off the back of a first in her heat that morning.
Fellow sprinter Theo Le Tissier showed promise for the summer ahead, competing in the U20 age group and producing consistently fast times through the weekend.
Firstly, the 16-year-old clocked identical 7.09s in both his heat and semi for the 60m.
He then ran an impressive series of 22.66, 22.49 and 22.62 for the 200m, the latter of which came in a final where he placed fifth.
Island Games 400m hurdles champion Nic Ackermann ditched the obstacles and put out a statement that the 50sec. barrier is likely to tumble on the flat this summer.
He came near his outdoor 400m best with a 50.19 heat before placing runner-up with 50.47 in a strange semi-final, where two of the six did not start, one dropped out mid-race and another was significantly off the pace.
Having made her own Island Games bow last summer, Amelie Carpentier was contesting these championships for the first time since moving out of the U20 ranks.
She took sixth in the senior women’s long jump with 4.82m.
