Vos out-dragged Leah Kirchmann (Liv Plantur) and Emma Johansson (Wiggle High 5) up the final slant into Stoke-on-Trent, leading home a bunch of around 21 riders.

In almost a repeat of stage 3, the multiple World Champion found herself again chasing Armitstead, Ashleigh Moolman (Cervelo-Bigla) and Elisa Longo Borghini (Wiggle High 5) in a breakaway this time with Johansson on the second queen of the mountain Oakamoor climb.
"We were riding full gas and we could see them but they were attacking each other. So sometimes they were making really high speeds and sometimes it came closer," Vos said.
Despite not cooperating so well, the four stayed away until the final kilometre when Vos decided to take a chance.
"The final kilometre was more up than I expected," Vos said "On Google Maps it looked a wide road and nicely through some roundabouts but it went "boom" uphill and they were still within 10 seconds.
"I decided to just go. I knew I had a chance in the sprint but there are still four in the lead you are sprinting for fifth and that wasn't really in my plan today," Vos said.
The reigning road World Champion finished fifth on the stage which wasn't entirely according to plan.
"From a team perspective, we had a good race, I had good legs again on the climb," Armistead said.
"In the final kilometre I could tell they (the peloton) were coming back and again Emma and Elisa attacked so I was just covering them and as the group from behind pulled, I tried to put myself in a good position but got caught out a little bit on the last corner."
Armitstead holds on to a eight second lead over Moolman, Borghini in third a further two seconds behind.
