After reading about the amazing 24 hour record of Dennis Klaaijsen (more than 700km) I tried to up my PR on distance as well as on the 1 hour. It worked:

1 hour 29,59 -> 35,67 km/h

distance 109 -> 166,76 km

Started with iSonic 122, 43 fin and 8.4 sail but after hour changed to 7,6 and 41 fin. Pffff The Grevelingen was really choppy with south  - southwest wind and this became really annoying after a while. Did some speed runs at Herkingen for a change in pace.

Even more respect to Dennis after today!
