The Grand Depart takes place in Brussels to celebrate the 50th anniversary of Belgian legend Eddy Merckx’s first Tour de France victory.
The race will then unfold over 21 stages, covering 3,460km, and features a series of flat days, time trials and mountain climbs.
Geraint Thomas is the defending champion but the Welshman says he feels under no pressure to retain his title.
“I’ve been super-motivated and pushing to try to win it again, because it was an amazing feeling winning last year, and I want to experience that again,” Thomas told 5 Live’s Bespoke podcast.
“I don’t feel pressure to prove that my win wasn’t a fluke, or whatever negative angle people want to take from it.
“It’s actually less pressure. If a rider hasn’t quite fulfilled their potential in Grand Tours they might be too eager, to attack too soon or too much, to get too emotional, but I think I can be more chilled, more calculated.
“Some people are saying I’ll be a one-hit wonder and all that stuff.
“It’s a pretty good hit to have, if you’re going to have one.”
All the action will be shown on ITV4 and Eurosport but some radio coverage is also available.
Fans can also keep up to date with the action using the official tracker.
