- 28 April 2010 – Porrentruy to Fleurier, 175.6 km (109.1 mi)
A hilly stage in the Jura mountains north of Lake Neuchatel. Two category 1 climbs and a category 2 – and a few other bumps along the way. Although the last 10 km are downhill, the course may be well suited to a break-away.
Peter Sagan – the up-and-coming young cyclist claimed the victory in the sprint. It was his third victory of the season. The win put him in first place overall as he was just 0.92 seconds behind the previous leader, Marco Pinotti. Sagan was pleased with the win, but pledged his loyalty to Liquigas–Doimo team leader Roman Kreuziger. According to Cycling News, Sagan said,
||Our team leader is Roman Kreuziger and I don't know what I can do. I'm not a good climber like he is. We'll see. There are three hard stages and a time trial to come
Sprinter Mark Cavendish could not hang in the mountains and was dropped from the peloton with 45 km to go. Had he not, a victory would have helped teammate Marco Pinotti remain in the leaders jersey.

- 29 April 2010 – Fribourg to Fleurier, 171.8 km (106.8 mi)
This stage looks to be for the sprinters. The course will pass through Fribourg twice before a flat finish. Although two category one climbs are listed they are tiny. The course will climb twice the locally famous and steep cobbled climb "Lorette." Anyone hoping to foil the sprinters will need to attack here.
