Bungee in harness trace for pulk or sled

One problem I’ve had with my harness traces is loading shock to my back.  I’ve tried a loop and drop method like this.

Whereas in the below video I show a harness trace design that doesn’t put a static line shock into my back.  This method is much nicer because the bungee almost completely prevents the line from ever becoming taut, the source of the shock.

When I’m towing my tire on a surface with a large drag force, above about 30lbs, having a bungee in the trace line is actually annoying no matter what.  The tire doesn’t slide at all, so with a smooth walking or skiing motion, there’s never any read shock.  But in the 5-25 pound drag force realm, where I expect to be in Antarctica, the sled or tire slides forward with my motion all the time, causing this problem.

With really heavy bungee, this seems to work quite well.  Also, another bonus is the line

and bungee don’t get snagged on anything, as they’re not dangling as in the above photo.  I definitely prefer this coiled trace harness bungee line method.

This is now my preferred method for reducing shock in a tow line.

Smoothing out the towing

After training for several months for an expedition to Yellowstone, I’ve been searching

 around for how others have changed the shock of dragging a tire or a sled.  As the rope pulls taught, the lower back and hips take the impact of the full weight of the sled or tire I’m towing.

This makes you a little tougher but over mutliple days, it’ll kill your back.

Enter bungees. Continue reading “Smoothing out the towing”
