Manager Shaun Derry admitted his squad is hurting after the 1-0 loss.
Notts’ incredible away record came to an end after Bradford City scored through Billy Knott before the interval.
The defeat meant the Magpies ended the year in 9th position.
Derry told Magpie Player: “We’ve been absolutely fantastic away from home and it’s been a mark of our success this year, but to lose it is disappointing, but we all knew it had to end at some point.
“Nothing lasts forever, but to lose it in that manner, with that type of goal we conceded was bitterly disappointing.
“It was more than an untidy goal to concede. We’ve been pretty smart defensive wise this year, but the lack of communication cost us dearly.
“We tried our best to get back into it, but we couldn’t break Bradford down. They kept the ball in areas which caused us problems.
“Our players have given us everything. They are so honest to the shirt and to all the fans that come to watch them, but I’m disappointed.
“We have to get back on the train and ensure the second half of the season is as enjoyable as the first half has been.
“We’ve got the league leaders next and this period of fixtures are difficult.
“We’ve got to make sure get the points on the board. The dressing room is low. The whole unit is tight and everyone is feeling hurt. We want the boys to reflect on a decent start to the season and I want them to come back fresh.”
Manager Shaun Derry also revealed he is looking to bring extra players in January and winger Stephen McLaughlin played his final game for the club and will rejoin his parent club Nottingham Forest.
