The race starts at 5am on Sunday with a time limit of 159 hours, which means you have to be back in Kigali by the finish party on Saturday (6 days and 15 hours later), cut off times for each CP will be published later.
If you don’t make a cut off time, of course you are allowed to finish the course on your own pace, you will still receive a finish in the ranking, although with an OTL.
