Spanish climber Óscar Sevilla who quickly opened a lead of several hundred meters. He was shortly followed by 's Dario Cioni, and as the climb entered its steepest final stage, the solo leader Ramos was caught and passed. A drive from the GC leaders in the group chasing Sevila and Cioni eventually led to the two being pulled in with several kilometer left to go, and as the climb approached the summit 23-year-old Spanish all-rounder Alberto Contador launched an attack up the hill that quickly gained a lead of 20 seconds, which was held until the summit and the finish. A notable underperformance of the stage was 's Paolo Savoldelli, 2nd in the GC that day, who suffered from diarrhoea and had to stop several times during the stage, and eventually lost 12 minutes on the leaders. Also Overall Leader Christopher Horner and local favorite Alexandre Moos were not able to keep up with the blistering pace on the final climb and both lost over a minute to stage winner Contador. Stage 4 – April 29: Sion–Sion, 127.7km Stage 5 – April 30: Lausanne ITT, 20.4km The stage was an individual time trial. Cadel Evans rode superbly in the last few kilometers, taking the provisional lead, and when General Classement leader Alberto Contador and close GC number 2 Alejandro Valverde both lost more than 50 seconds to Evans, the Australian all-rounder rode to overall victory.
