Is it possible to bring in fill? In a truck? That would help a lot.
The picture appears to show the eroded section directly on the fall line, is that correct?
Evaluate how far you have to divert water to keep it out of your problem area. Start at the top of the slope, dig a channel (use the spoil to build up the downhill side) at a ~45 degree angle to the slope. Use some of the spoil to fill across the proto-ravine to divert water into your drainage channel.
Repeat the process at several points down the eroded trail. Obviously, this will only work in the heavily eroded area if you have a bunch of fill to bring the bottom up high enough to roll the water off to the side of the trail. The limiting factor is how much fill you can move, then secondly how well you shape it to keep the same thing from happening again.
The idea is to divert as much water as possible from the top of the trail, before it rolls down into the eroded section.
You'd be better off if the trail could be relocated somewhere else, and the repaired section was allowed to grow vegetation to hold it together.

), otherwise it will move to another spot and/or wash out the fill, just as it has done. Having done that, you can fill the groove with gravel, stone, or even busted out concrete, add a topcoat of suitable soil or other amoring, depending on the site.
