Ultra long distance rides

Is there anything preventing ultra long activities (like 600km brevets) that take more than 24 hours from being considered? I noticed I am missing those and it totally messes up stress, because I dont do any hard training for a week or so after. I did use a power meter, I was surprised to see the activity not showing up at all.

We have had these processed in the past. If you can forward us the FIT files to support@xertonline.com, we can look to see if there are any memory issues that have crept in since we last addressed the issue.
