It's Cav's first race after fracturing his shoulder in the now infamous run-in with Peter Sagan's elbow on stage four of the 2017 Tour de France.
But the Manx Missile found bouncing back from this injury a challenge, especially after recovering from mononucleosis for the first half of the year.
"I've always been fortunate that I've got a mind-set I can bounce back from injury, but this time was quite hard," Cavendish said at a Tour of Britain press conference.
"I have to be realistic. I'm not a machine. I'm not looking at individual results here, but as part of Dimension Data we can get results.
"It's not often we get to race at home, so to come here, it's always something special to come and experience it, to absorb the atmosphere."
Australia's Caleb Ewan (Orca-Scott) is also making an appearance at the race hoping to put on a sprint show on top of the strong form he displayed at last month's Tour of Poland.
"It’s been a long season up until now, but I’ve had a good break in the middle of the year so hopefully my form has come up good for this," Ewan said.
“The courses here tend to suit me really well with the punchy climbs. The fans here are awesome, there aren’t any other races except the biggest ones that have so many fans.”
