You were slow b/c you accidentally ended up over your heads.
Another rider might have been slower still, on account of having crashed out. Anytime you go around a blind corner, or over a blind hump, you have to assume there can be an obstacle waiting to surprise you.
If I realized my mistake early enough, I might try to walk the bike back, off or right at the edge of the track. If I’m too far in, I’d push ahead best as I could. And be ready to get off the track if I heard someone catching up.
