The route for the road race was one of the hardest courses ever for a World Championship, and Olano showed his stamina by riding the last kilometer solo with a flat tyre.
In 1998, Olano won his only grand tour, the Vuelta a España,[2] fighting off furious challenges from mountain specialists Fernando Escartín and Roberto Heras as well as fellow all-rounders Laurent Jalabert and Alex Zülle, all at the height of their careers.
Banesto's own mountain specialist José María Jiménez took 4 stage wins, on several occasions leaving Olano alone on the climbs, and even taking the Yellow Jersey from his team captain.
Olano won back the jersey on the second time trial, but the events and subsequent media speculation soured his relationship with Banesto, and he decided for a switch to the ONCE team for the following season.
In the prologue, severe rains put the late starters (including most of the GC contenders) at a big disadvantage, but Olano nevertheless managed to take 2nd place.
In the stage 7 time trial, Olano won with a clear margin to main challenger Jan Ullrich, taking the top spot on the GC and the Yellow Jersey.
[2] On account of results early in his career, a Basque background and some physical similarities, Olano was seen by many supporters as the successor to five-times Tour de France winner Miguel Induráin.
However, he was a reluctant climber, and a tendency to lose valuable time to the specialists on the steepest and highest climbs, would keep his number of Grand Tour wins to one.
[2] He was fired from this position after a report from the French senate revealed that he had delivered a suspicious sample during the 1998 Tour de France, indicating use of EPO.
