Cheltenham Town missed the chance to extend their lead at the top of League Two after a 2-0 home defeat by Barrow.
The Bluebirds completed a win double over the Robins with a goal in each half.
The first was low cross from James Jones on the right which Ben Tozer missed before it evaded Josh Griffiths and crept inside the bottom left corner after only two minutes.
Barrow added a second in the 66th minute when Bobby Thomas' long throw was kicked against Sean Long by Griffiths and it flew into the net for an own goal.
Cheltenham were close to leveller in the first half, with Chris Hussey's shot coming off Sam Smith's head before hitting the post.
Hussey also forced Joe Dixon into a diving save, with efforts from Alfie May and Smith kicked off the line.
But they ran out of ideas in the second period as Barrow became the first team since Stevenage in May 2019 to record a League Two double over Michael Duff's side.
Cheltenham play Salford City at home on Saturday.
