Colney Heath Ladies were just seven minutes away from completing the treble this season - only for Stevenage Res to break their hearts.
The Magpies were 2-1 in front going into the final stages of the Herts Women's Trophy final, looking to add to their Beds & Herts League Premier Division and league cup triumphs.
However, Boro pulled level in the game at the County Ground in Letchworth before grabbing a last-minute winner for a 3-2 success.
Stevenage had actually taken the lead in just five minutes, Ella Mercer's free-kick stopped by a good save by Rachel Sherlow, but the rebound was forced home by Isobel Matfield.
Mia Simmonds was denied by Stevenage keeper Mia O'Brien but at the other end, Sherlow was required to pull off four excellent saves to prevent Stevenage from doubling their lead, the best of them tipping a Mercer shot over the bar.
But before half-time arrived, Colney turned the game on its head.
Amy Phillips fed Cally Salter to shot over O'Brien on 43 minutes for 1-1. Then a minute later Anna Simou found Phillips and she fired inside the near post to put the Magpies in front.
Sherlow was required to be at her best on several occasions in the second half, as Stevenage threw all they had at Heath.
And the pressure paid off with seven minutes to go, Anaise Corrigan breaking through the middle to equalise.
Holly Jury, Madison Gorton and Laura Gifford all tried to win it for Colney but it was Stevenage who found a way through, Amana Oguntuga poking home a loose ball in the box to snatch the trophy
The final game of the season for all St Albans Primary School squads was played by the girls as they hosted Croydon in the London League Super 6s.
After a really tight and even first half, with Croydon having more of the ball but St Albans looking dangerous on the break, the second half burst into life when top scorer Lara Taylor scored her 11th of the season.
Croydon equalised soon after and the match looked like it was drifting into a draw with St Albans defending brilliantly.
They were still looking for a goal on the counter but three goals in five minutes meant Croydon took the points back with them.
A spokesman said: "It was a valiant display by the St Albans girls who once again proved they can compete against any team they play.
"They have represented St Albans Schools in the best possible way all season and we are very proud of them."
