Opening day of the Czech GP at Brno dawned under a steady rain, though with mild temperatures. The FP1 session was run on a full-wet track with Marc ending in P2 and Dani in P4.
Weather conditions improved over the course of the day, allowing the riders to switch to slicks and a dry setup for FP2, although the track was still a bit patchy in spots at the beginning of that session. Dani closed the day in seventh place, Marc in 10th. Neither rider fit a new tyre at the end of the session.
