Thomas, who is riding for Team Ineos, won the general classification in 2018 and thinks he is in good shape to get a second yellow jersey.
The famous race, scheduled to take place between June 27 and July 19, has not yet been postponed or canceled, but with sporting events around the world, his chances of surviving as expected seem distant have been affected.
Thomas appreciates that the Tour should take its place in the bigger scheme of things – and has announced its own grueling charity race to support the NHS – but he is still crossing his fingers for the event.
“I think I’m in great shape right now,” he told BBC Radio Five Live.
“My road career started a little later than most because I raced on the track and at the Olympics. I feel like these are my best years. It’s a bit of a shame at the moment but there are a lot of serious things that need to take precedence over that.
“It is a shame but I hope it can move forward. Obviously, there are more important things that need to be sorted out first, but as soon as they are safe and ready to go forward, we would like that to happen. I pray and hope it will happen at some point.
“This is the pinnacle of the sport, that’s what it is about. I don’t know when, but I hope it will continue this year. ”
Thomas, meanwhile, has announced that he will undertake three 12-hour “shifts” on his indoor training bike as part of a fundraiser for the NHS starting April 15.
“I wanted to help as little as possible. All I know is riding a bike, so I thought I would reflect the schedules of an NHS worker, “he said in a video on Twitter encouraging people to join him and to to contribute.
“I’m going to be here in my garage on Zwift, and I’m going to do three shifts of 12 consecutive hours starting Wednesday and ending Friday evening. All the money goes to the NHS.
“I’m a little nervous because I didn’t drive that long the day before, so I’m going to be pretty sore at the end of the first day, not to mention the third day. “
