The party is awoken at dawn by a pursuing party of goblin wolf riders, they move quickly amongst the party and use hit and run tactics.
They will try and slow the party, laughing to each other that the rest of the warband is only a few minutes behind and they have overwhelming numbers.
Make clear to the PCs that if they dispatch the wolf riders there is no way they will be able to best an entire orc warband of hundreds of warriors. They must run!
The chase will last 6 rounds. Each round the orc warband will move one step closer to the party.
The party will need to over come 6 complications testing a range of skills in order to escape. The PCs will roll individually for the skill checks and can narrate their own way of doing things.
If they reach the final stage before the warband catches up with them, the chase will end.
