  1. Just to register how upset I am with the organization of Saiko Ecomarathon Fall 2019. I have registered and paid usd 45,00, and they cancelled the race and Announce only 2 days before. I already had all my logistics prepared and hotel paid and schedule open just for that. Money was not refund and nothing officially informed about the cancellation.
    Very unprofessional and not committed to racers that trusted and took serious joined the run. I don’t recommend any event organized by them.
