The flagship daily pulled out the stops in the run-up to the event and on the weekend of Le Grand Depart by bringing out five supplements and publishing on a Sunday for the first time since the funeral of Princess Diana.
JP has now revealed that the paper added 8,349 sales on Saturday 5 July – an increase of 14.6pc on the previous week.
And across the week the series of supplements helped boost the overall performance by an extra 12,696 copies.
Saturday’s paper included a special souvenir edition of the paper’s weekly magazine, while in the week beforehand there was a 68-page8-page Tour de France-themed Yorkshire Vision glossy magazine.
Circulation figures from the Sunday edition – only the second such edition in the paper’s history – are not yet available.
Richard Thomson, group sales and circulation director at Johnston Press, said: “The Yorkshire Post managed to completely own the local media coverage over the weekend – both in print and online – and the boost in sales figures is a real testament to the incredible efforts of the whole team there.
“The coverage was second-to-none and obviously appreciated by both locals and visitors across the county.
“Sunday’s special edition – which featured a spectacular image-led wraparound, has also proved to be a huge success and is still selling well.”
The Yorkshire Post website also had a 62pc uplift in visitor numbers and 131pc uplift in page impressions over the Grand Depart weekend.
