I've done it recently, and here's how I did it:
Tip 1: BRING A SPIRIT TERRORBIRD!
Running out of energy while getting back to the start is absolutely miserable, trust me.
Tip 2: LOG OUT DURING VAMPIRE ENCOUNTERS!
I can't stress this enough. An update made them incredibly difficult to kill, and NONE of the adventurers will attack them. Battles last forever, and you can die! Logging out takes you back to the begining of the minigame instead of the swamp, so you can start over and pray you don't encounter them again.
Tip 3: RUSH EASY PATH REPEATEDLY FOR THE HARD DIFFICULTY ADVENTURERS!
They suck. They barely attack, and when they do, they die. Just rush easy path again and again until you get them to be able to predict what's going to occur in the path, then choose hard if the path hint doesn't contain any enemies.
Tip 4: ALWAYS CARRY 4 PINEAPPLES!
Sometimes, you get the starving camp event, and it takes way too long to kill and cook food. Simply bring 4 pineapples, and cut 2 into slices, and feed each individual slice to the campers.
Tip 5: DON'T BRING ANY FOOD! BRING A SHIELD AND WEAR FULL GANODERMIC + POLYPORE STAFF, ABYSAL WHIP, AND GRANITE SHIELD!
Food after Eoc is largely redundant with the large supplies of health the armour gives. Simply use rejuvinate and regenerate to heal yourself. Why bring the whip? So you can attack while using rejuvinate.
Tip 6: TRAIN JAYENE KLIYN FIRST TO 99!
This unlocks the "Ouroboros pouch", which acts like an infinite druidric pouch so you dont have to carry that weak sickle.
And if you think I'm making this up, here's a screenshot of my progress here:
