cleared codes 2009 Jetta Wolfsburg. Want to revive MIL so codes show again.

Check engine light came on. Code reader displayed P0101, P0121, P0221 and P0172, Related systems had been repaired/replaced in last year. I mistakenly cleared the codes and now I need to do a drive cycle to restore MIL. Have cycle list. Do all items need to be done with no other driving in between? Do not know where you could park and let the engine become cold, start it and then accelerate to 55. I would probably need to drive 5 miles after #2 before I could do #3. Would also need to stop or turn around between some tests. Tests would be around 94525 where it is registered.
