Before that Thomas will pull on the lycra and clip into his pedals for one final race.
The six-day Lloyds Tour of Britain starts in Suffolk on Tuesday, 2 September and finishes with two stages in Wales.
Sunday’s Newport to Cardiff finale is the perfect setting to end the near two-decade career of Wales’ most successful cyclist.
“I’m really looking forward to it,” said Thomas.
“Obviously it’s going to be a mix of emotions, it’s all I’ve done for 19 years so come Monday morning after the finish in Cardiff it’ll be strange waking up with no goals or targets racing wise, that’s going to be strange.”
Ten stage race wins, three World Championship victories, Olympic triumphs, a Commonwealth gold medal and numerous other successes later, he will finally pull off a race number for the final time.
“I just feel so lucky to be able to call time on my career on my own terms, you know when I’m finishing and even more lucky to decide where as well,” he added.
“The fact that the Tour of Britain is in September at the end of season and the last stage is into Cardiff is just unreal really.
“I think they’re planning some event afterward in Cardiff Castle as well so it’s going to be nice to say thanks to the fans as well.”
It will not be the first time the Welsh capital’s historic setting has paid tribute to the man who in 2018 won both BBC Wales and the national BBC Sports Personality of the Year award.
That year thousands lined the streets to welcome home their yellow-clad Tour-winning hero.
“That’s probably the highlight of everything I’ve done off the bike really, that homecoming in Cardiff,” said Thomas.
“Because I live away, since I’ve been a pro, outside of the UK you don’t really get an appreciation of the support you get.
“Obviously I know it’s a massive amount and I get a massive amount on the road but then to go back to Cardiff and to have that was just insane.”
Similar scenes are expected next week, but once the fuss has died down and before he takes up his new roles Thomas is already planning more time with wife Sara and son Macs.
A first ever skiing holiday – out of the question during his racing career – has been booked.
Before all of that there are just 886km (553 miles) to race, six more days of sweat and maybe one or two more tears.
“I think so,” Thomas admitted.
“I was always winding up Sara – because she’s quite emotional, more emotional than me – and I was winding her up about crying at our wedding, and I was the one that cried the whole time!
“Obviously in the Tour de France [win in 2018] it was a similar thing. I never thought about the end, it was always about each day and then suddenly it got to the time trial and I’d won it and then it hit me.
“That’s when I ended up crying obviously on international telly, so I think Sunday could be similar.”
