The Dutchman did a seven-hour indoor session, coming just a few days after his outdoor trainer session with a view at his home in Andorra.
Gesink still has some way to go to match Astana rider Laurens De Vreese, though.
On Friday, the Belgian put in the longest turbo trainer session we've seen yet, logging a giant 370km ride on a virtual version of the Yorkshire Worlds finishing circuit. The 31-year-old spent over 11 hours on the trainer, in a ride titled the '#OliverNaesenChallenge'.
"Show your fighting spirit Against covid-19," De Vreese wrote on Instagram, showing off his ride data and set-up in photos and a video.
Last week, AG2R La Mondiale rider Oliver Naesen rode a mammoth 365km around East Flanders, where outdoor riding is still permitted. Lotto Soudal men Thomas De Gendt and Jasper De Buyst put in a real-world 300km training ride at the weekend in honour of Milan-San Remo.
There has also been plenty of other online riding, too. At the weekend, RCS Sport and Garmin organised an online ride of the final 57km of Milan-San Remo.
Several past winners, including Vincenzo Nibali and Maurizio Fondriest, took part, as did 2019 Tour of Flanders winner Alberto Bettiol, and former world champion Alessandro Ballan.
Elsewhere, both the Mitchelton-Scott and Israel Start-Up Nation teams have hosted indoor rides so far, with ISN running a virtual Stay at Home ride on Zwift featuring André Greipel and Alex Dowsett on Friday night.
Mitchelton-Scott, meanwhile, are running a full series of online events, named BikeExchange – Where the World Rides. Simon Yates and Annemiek Van Vleuten are among the riders to have taken part so far.

In honor of @Milano_Sanremo @JasperDeBuyst and i did a 300km ride, connecting some of our biggest cities. Too bad we had a 120km headwind from Mons to Antwerpen. pic.twitter.com/taAMtMr4SGMarch 21, 2020
