April Tacey took her second win at the women's virtual Tour de France, the 19-year-old Brit sprinting past Anna Henderson (Sunweb) and Lauren Stephens (Tibco-Silicon Valley Bank) on the line.
Stephens team-mate Leah Dixon then took fourth while Chloe Dygert (Twenty20) rounded out the top five.
Drops now sit less than 50 points behind Tibco - Silicon Valley Bank in second place in the general classification, with Jos Lowden having worked hard to solidify the team's lead in the polka dot jersey competition throughout stage four.
The Casse-Pattes stage, which translates to 'leg-breaking', was the fourth of six, with next weekend's final two stages culminating on the Champs-Élysées in Paris.
How it happened
Two 23km laps make up stage four's 46km course, with the bigger of the two category three climb placed just before the finish.
Jos Lowden and April Tacey were the first two across the line of the first category three climb as they looked to defend the polka dot jersey from Ceratizit WNT.
Ashleigh Moolman-Pasio (CCC-Liv) was one of 10 riders dropped early, before Sarah Gigante (Tibco - Silicon Valley Bank) and team-mate Lauren Stephens led the favourites for the stage up the second climb of the circuit, Chloe Dygert pictured gurning away in her pain cave.
The race began to split apart up towards the summit, with Lowden first over line, followed by Romy Kasper (Parkhotel-Valkenburg) and then Dixon.
Chloe Dygert was the next surprise rider to be dropped from the group, with only 12 riders left on the front. But with the pace slowing slightly, the American would get back in alongside a number of others just past the halfway stage.
The front group containing the favourites had pulled out a 45-second gap, meaning these 17 riders would likely contest the win, with 18km remaining.
Tibco-Silicon Valley Bank looked to hold the advantage heading towards the business end of the race, as Stephens, Dixon and Gigante all remained in the front group.
Stephens led Dixon across the line of the intermediate sprint point without much bother, the riders biding their time before the two climbs and sprint finish to come.
Lowden once again took maximum points under the Pont du Garde at the first of the two category three climbs, further solidifying Drops' lead in the Queen of the Moutain competition.
Onto the final climb, the pack was tightly bunched as the gradient increased. Sarah Gigante then started to test her rivals, stretching her legs at the front, stringing out the group behind, with team-mate Stephens sitting on her wheel.
Gigante then went again, pushing out 330w as she escaped off the front of the group towards the summit. Stephens and Dixon were the next two behind, odd tactics even for the virtual world.
This allowed Jos Lowden to use a feather power-up and take maximum points at the top of the climb, an exemplary performance on stage four from the Brit.
Heading into the final 4km it was all downhill until the sprint for the line, a number of riders catching their breath with a super-tuck, the group having split just after the climb but coming back together with 2km to go.
Sunweb's Anna Henderson led under the flamme rouge, Lowden in her wheel while Dygert sat on the back.
Leah Dixon was the first to open up her sprint with an aero power-up, but April Tacey once again timed her sprint to perfection, coming past her compatriot and stealing a march on her rivals once again, sneaking through the gap to pip Henderson and Stephens on the line.
