The Duo Normand is the main focus for Team Grumpy. Run annually in September/October, it's a 2-up team time trial that attracts a large number of teams drawn from local clubs, from the UK (especially the Channel Islands), and from the rinks of the Elite UCI-registered teams.
Team Grumpy rode in the Duo Normand from 2003 to 2019 (except in 2007).
The appearance of Covid-19 in 2020 lead to the cancellation of the 2020 event, and the Duo Normand has not restarted since (as of 2023). There was an odd event which paired a short run and a short 2-up time trial in May 2022, but this didn't seem to attract much interest.
Team Grumpy still hope that the Duo Normand will reappear on the calendar of events!
