After a start under clear blue skies in Hemel Hempstead, the race exploded into life – as did the rain clouds – with an aggressive start to the stage and Cannondale Drapac in particular making several attempts to put riders up the road.
In the end two groups of three riders went away, but with neither a threat to the overall they were allowed to merge and build a four-minute plus lead, with Jacob Scott extending his SKODA King of the Mountains lead as a result.
With the race entering the Cotwolds and the gap just over the three minute mark, Tiago Machado sparked the attacking, going clear of the peloton but not quite making it to the leading six.
Behind him a strong five-rider group made an attempt to work their way across, including his Katusha Alpecin teammate Reto Hollenstein, Michal Kwiatkowski, Sylvian Diller, Ryan Mullen and Dowsett. The five got 30-seconds clear of the peloton, but with Lotto NL Jumbo alert to the threat to Boom’s lead began to work hard bringing the whole race back together.
This immediately spurred another Katusha Alpecin into action, with World Time Trial Champion Tony Martin driving clear in heavy rain on an impressive, and sustained, solo effort, but one that was ultimately doomed under the Lotto pressure.
With everyone back together the intermediate Eisberg Sprint at Winchcombe became the new general classification battleground, with BMC’s Stefan Küng grabbing the bonus seconds to elevate him into second overall – between Boom and teammate Victor Campenaerts – while Mark McNally took two points to leap him over Graham Briggs and into the Eisberg Sprints jersey.
On the day’s final SKODA King of the Mountains climb at Cleeve Hill, topping out with less than 10-kilometres remaining five riders went clear including former winners Boasson Hagen and Dylan Van Baarle.
Van Baarle then crashed out on the descent, obstructing Laurens De Plus and leaving Dion Smith, Gorka Izagirre and Boasson Hagen out front. With the teams of the sprinters sensing the chance of success again – that earlier in the day had seemed highly unlikely – they came to the front on the final five kilometres in Cheltenham, reeling the trio in just before the final kilometre arch.
