Stairs with 20lb pack. Only managed 5 minutes of double stairs - the weight in the pack made it really hard. And even at that I had to use the railing to get up on a lot of the steps. Not sure which is more beneficial - heavier pack but only single stairs or light pack with double stairs. Took occasional 30 second breaks to check in on Rootstock who are at Untamed New England - dot watching is so addictive.
