We hope you're already on your way before the 20th!
Don't wait too long to get started on this. Make sure you have a sturdy bike bag with lots of padding to keep the shiny bits shiny and the carbon bits intact. Wrap your disks, derailleurs, brake levers and anything else that might get broken with lightweight foam or something similar for the best chance at having everything arrive in Costa Rica in working order.
Registration will remain open until all 100 spots are filled. It won't take too long to fill all 100 spots so register ASAP!
