Same as every season in recent memory, not all cyclocross riders are full-time focusing on it. I thought it would be good to create an overview of what the plans of the top riders are. Maybe mods can pin a list or something. Please feel free to add info you have as interviews are often local.
Men
Let's start with the men. Top 10 UCI rank is:
1. Niels Vandeputte - started season in Dendermonde
2. Mathieu Van der Poel - Not sure, but probably only 5-6 crosses
3. Thibault Nys - starts November 1st. 18 races scheduled
4. Michael Vanthourenhout - started and won in Dendermonde
5. Tibor Del Grosso - Not started yet, not clear when but probably soon
6. Joris Nieuwenhuis - Not started yet, but confirmed for X2O so November 1st definitely
7. Felipe Orts - starts in woerden on october 20th
8. Toon aerts- currently recovering from injury.Targets worlds in Ostend.
9. Laurens Sweeck - started season in Dendermonde
10. Emiel verstrynge - target mid december (Glasgow?) and +-15 races
Interesting to note that only 3 out of 10 started in Dendermonde.
Other interesting riders yet to start:
1. Wout van Aert: not clear yet, but rumored to ride more then the 8 of last season
2. Tom Pidcock: Won't race. Probably never again in cyclocross.
3. Tim Merlier: None or a local training ride at max.
4. Quinten hermans: Target end of november for a (small) comeback
5. Gianni vermeersch: 5-6 crosses with Belgian champs as target. No worlds
Will do women in separate post. Reddit editor is horrendously slow here.
