Actually, Michigan has a significantly long history of announcing the their TCC a whole year in advance, just to avoid such date conflicts.
They announce during, &/or just after, the prior year's event.
Dates of the national and European tree climbing championships as well as the World Championship (ITCC) and the European Championship (ETCC) in tree climbing. A championship date is still missing? Simply send us a hint per E-Mail or via Facebook. Thanks!
