Question: How old was Tom Dumoulin when he raced in 2018 in Rome? Passage 1:ChicagoFest, started by mayor Michael Bilandic, was the precursor to the Taste of Chicago. After Bilandic's tenure in office, newly elected Mayor Jane Byrne attempted to end the festival as well as many other programs associated with the former mayor. Many Chicagoans disapproved of Mayor Byrne's attempt to stop the festivities (although attendance at ChicagoFest had begun to wane). She and her successor, Mayor Harold Washington, dedicated more time and energy to promoting the Taste, slowly phasing ChicagoFest out in the process. Mayor Washington finally put an end to ChicagoFest when in 1983 it was moved from Navy Pier to Soldier Field and attendance continued to wane. The popularity of the Taste of Chicago has prompted other cities to spawn numerous offshoots and equivalents throughout the United States, such as the Taste of Champaign, CityFest in Detroit, the Taste of the Danforth in Toronto, the Taste of Kalamazoo, Taste of Addison, Taste of Denver, Taste in Dallas, Taste of Madison, Taste of Austin, the Taste of Peoria in Peoria, Illinois, and the Bite in Portland to name a few. The first "taste of" festival was Taste of Cincinnati in 1979.
Passage 2:On his first appearance as a three-year-old, Lanfranco started 10/1 third favourite for the 2000 Guineas at Newmarket on 4 May but looked completely outpaced and finished seventh of the fourteen runners behind Shadeed. Later that month he was moved up to one and a half miles for the Predominate Stakes at Goodwood Racecourse. He started favourite and won easily by three lengths from Phardante. In the 206th running of the Epsom Derby on 5 June Lanfranco started at odds of 14/1 in a fourteen runner field: Henry Cecil had doubts about running the colt as he felt that the prevailing firm ground would be to his disadvantage. With Steve Cauthen riding the Cecil stable's main hope Slip Anchor, and Piggott opting to ride the Irish-trained Theatrical Lanfranco was ridden by the American jockey Cash Asmussen. On a course which, according to Cecil, did not suit the colt, he finished fifth behind Slip Anchor, Law Society, Damister and Supreme Leader. Timeform opined that should have been aimed instead at the Prix du Jockey Club in which Mouktar was "the only top-class horse" engaged.
Passage 3:Froome entered the 2018 Giro d'Italia as one of the favourites to take the overall victory in Rome at the end of May. Once at the start of the Giro d'Italia, he was he would be cleared of his offences. However, before the race could even begin Froome crashed whilst performing a recon of the opening time trial in Jerusalem. Froome would finish the time trial in 21st place, ceding 35 seconds to overall rival Tom Dumoulin. After the race, Team Sky directeur sportif Nicolas Portal admitted that the injury Froome sustained in the crash was worse that they had stated at the time, and Brailsford said that the crash was a setback to Froome's physical condition, which the team felt was below the required level at the start of the Giro. By the end of the first summit finish on Mount Etna, Froome had risen to eighth overall, one minute and 10 seconds behind early race leader Simon Yates. On stage 8, Froome fell on his injured side when his rear wheel slid on a wet climb. By the end of stage 9 to Gran Sasso d'Italia, Froome had lost a further one minute and 17 seconds to Yates, dropping to 11th overall. Stage 10 could have also proven ominous when afterwards he admitted to feeling pain and an imbalance between his legs; and was glad to maintain his position. Froome's first signs of recovery came through on the most difficult climb of the race to that point, Monte Zoncolan, where he distanced all of his main overall rivals, taking the stage win. Froome's deficit to the maglia rosa was now 3'10". However, on the final climb of the following stage to Sappada Froome cracked, yielding more than a minute to the other main general classification contenders. Overall, Froome lay 4'52" from Yates, the leader, 2'41" from Dumoulin, 2'24" from Domenico Pozzovivo and 2'15" from Thibaut Pinot.
