My experiences with chest running in DoA have been this.
Stygian Veil: 1-2 chests near the whispers. If one chest spawns behind the gates, you can take the quest and wait for the hungers to run out...then sprint by them (or whatever speed buff you have) and get the chest.
Ravenheart Gloom: also 1-2 chests normally. Just use your mini-map and speed around the groups, peering to find chests. Normally found near the back, and fairly easy to get to without aggro.
Hope that helps.
