There are similar rainfall forecasts in the Hongcheon and Yangyang Seorak Granfondo course areas. It is 0 ~ 2mm in terms of rainfall per hour. The wind speed is 2 to 4 meters per second.

It is considered that there is no problem in the event according to the weather forecast. However, it is anticipated that bad conditions such as low temperature, slippery road surface, fog, etc. will cause bad weather.

The organizing team has a total of 100 security personnel at major crossroads and hazardous areas, 15 ambulances and 15 motorcycle marshals carry ambulance kits and support their players.

At 82km from the starting point, the Granfondo course cutoff is at 12:00, but if you pass after 10:30 it is highly recommended to ride the Mediofondo course as much as possible.

There are various opinions for each athlete such as the time of departure adjustment and the shortening of the course, but please understand that it is difficult to accommodate the opinion of all people.

Thank you.
