The list seems to be growing with potentially at least 10 more races than last year. The Sri Chinmoy Marathon team will hold a Self-Transcendence 24 hour in Russia again later in the year making it by far the worlds number one sponsor of 24 hour and multiday races.
Some websites I have trouble with because of my lack of that language. I am thinking of the Korean Ultra website as a particular example. There are a lot of ultras taking place in Korea and the website seems to be working and have the information but it’s not in a useful format for me right now. If anyone would like to send me a list of Korean ultra events 24 hours and up, I will be very happy to list these races. And I may as well add that any other 24 hour races not listed is due to my ignorance and I am willing to be enlightened.
Some Korean dates I found on the IAU’s calendar which was a great help.
There are some great calendars around covering the ultra scene – more now than last year. If you are moving around and want to check out some races this list will give something to think about.
