Edge 840 froze during 8 hour MTB race - Ride saved but ZERO training effect. How can I get this fixed!!!!!

The freeze is frustrating, not the first time. But no training effect is even more frustrating,. How can there no be a way to fix this manually? You can how much work was done during the ride and almost all my time was in tempo, but I get nothing so now I'll need to ignore my status for the next month!
