Plymouth cyclist Jonathan Tiernan-Locke will not defend his Tour of Britain title when the 2013 edition of the stage race takes place next month.
Instead, the 28-year-old is focused on late-season events which will include the Tour of Beijing in October.
Tiernan-Locke signed a two-year contract with Team Sky, one of the top World Tour teams, after winning the 2012 Tour of Britain in impressive style.
The 2013 edition starts in Scotland on Sunday, September 22, and will visit Devon on Friday, September 20.
The 137-kilometre stage six starts in Sidmouth and will pass through Honiton, Tiverton, Exeter, Chudleigh and Bovey Tracey before finishing at Haytor on Dartmoor.
It will be the first mountain-top finish in the history of the Tour of Britain.
Tiernan-Locke said: "It [the Tour of Britain] was never in the programme.
"I don't feel like I'm missing out as such as I was never down to do it.
"Obviously, it's a race that I love. I have done it three times now and each one of those I have really enjoyed – culminating in last year's result. But I'm sure I will be back to do it again one day."
It had been intended for Tiernan-Locke to make his Grand Tour debut in the Tour of Spain, which started on Saturday and continues until September 15.
However, fatigue following a tough start to 2013 meant that he was not included in Team Sky's squad, which is being led by Colombian duo Sergio Henao and Rigoberto Uran.
Instead, Tiernan-Locke had a spell away from the bike before returning to action in the one-day Vattenfall Cyclassics in Hamburg, Germany, at the weekend. He was 137th out of 164 finishers, more than six minutes adrift of Germany's John Degenkolb, who won the event.
There are three Grand Tours each year in professional men's road cycling – the Giro d'Italia, the Tour de France and the Spanish event. They are regarded as the pinnacle of the sport, and cyclists have to be at their peak to compete in them successfully.
Tiernan-Locke said: "All through the year I had this goal in mind of reaching mid-summer in great form and going for the Vuelta [the Tour of Spain]. But, for whatever reason, mainly down to the training I undertook and not recovering enough after races, I arrived at mid-summer cooked.
"Three weeks racing the bike is not something to be taken lightly. At any level, it's difficult, but at World Tour level especially so.
"You don't want it to be a bitter memory of just surviving for three weeks. You need to be going well just to do your job and be useful to the team.
"Leading up to the race [the Vuelta], I had come completely off the bike to get over the fatigue and reset myself.
"Obviously, I had lost some training but I feel pretty decent on the bike again now."
In yesterday's third stage of the Tour of Spain, Uran finished fourth on a dramatic day which saw RadioShack's Chris Horner take a fine solo victory and claim the overall lead.
Uran crossed the line on the uphill finish at Mirador de Lobeira three seconds adrift of the veteran American and also behind Alejandro Valverde (Movistar) and Joaquim Rodriguez (Katusha).
Horner has an eight-second advantage over Vincenzo Nibali (Astana), with Uran in seventh, 25 seconds back, in the overall standings.
