I'll put in my two cents..
I'm a solo runner to anywhere you could possibly want to go.
Like others have stated before, timing is everything.
I use to use mending > but have since changed it out for shielding hands.
Also when I run the worm never follows me unless I'm running with someone else, then they tend to follow.
Try this and tell me if it works for you.
If you can keep up with the group of imps that race off towards the tunnel your timing will be on point - sprint, charge, sprint, charge to keep up.
If you manage to keep up and don't have to wait for them to pass, then at the bottom of the hill u will get knocked down.
I prefer to hug the left side of the wall in the worm tunnel so I suggest you do the same.
Once you are standing again balance stance, jog until the worms pop up again and charge out, (practice this).
It is scary at first, but you have to then (using sprint) sprint out of the tunnel and stay huging the left wall or shoot over to the right (depends on spawn).
Endure pain if you have to when you reach the golems. once balanced stance returns use your sense and turn it on and charge out once again.
Not to make it too easy by telling you when to use it, but practice using shielding hands in diff possible combo's, you will find it for getting through mobs with 0-5 dmg >

.
The rest of lomars is cake as the first part is where I have seen many runners die.
If you want me to critique your running let me know
