The Etixx - Quick-Step pairing were already ahead after day one and increased their lead on day two

Iljo Keisse and Michael Mørkøv (Etixx – QuickStep) retained their lead on day two of the 75th Ghent Six.

Thanks to victory in the final derny race, the pair extended their previous lead of eight points to 11 over the Lotto-Soudal pairing of Otto Vergaerde and Jasper De Buyst.

During the second Derny race, the Lotto duo did threathen the leaders with De Buyst winning plus a strong showing from Vergaerde, but in the end it was only enough to hold second rather than gain on Keisse and Mørkøv.
