The mission itself is very easy. You don't even need henches to do the portals, or any speed skills for that matter.
This is what you do:
1. Immediately run to the first crystal, grab it and 'tag' the closest portal.
2. Grab the next crystal, and tag the second closest portal (if you're really quick you'll get there before them. If so, wait till they've attuned it and started running back).
3. Grab the next crystal, and tag the most distant portal.
4. Grab a final crystal, and tag the second closest portal again.
Done.
If you totally screw up & give them time to get to the furthest portal, start from 3 again.
Do NOT stop to fight, just keep running.
The bonus requires you to do like aB- says, and is considerably harder.
