In the 1997 World Championships, Radcliffe finished in 4th place over the 5,000 metres. Wami again outsprinted Radcliffe in her final race of 1997, in the Brussels cross country event. Radcliffe had dropped out of Durham's cross country race with flu at the start of 1998, but bounced back to finish third in Dublin. At the 1998 edition of the World Cross Country, Radcliffe again won the silver medal. Radcliffe set a new world best for on the road around Balmoral Castle. At the European Cup Radcliffe, captaining the team, won the 5,000 metres and finished second in the 1500 metres. Radcliffe set the pace in the 10,000 metres at the European Championships, but finished fifth. Radcliffe, who was suffering from a virus, took some time off, before returning to the cross country discipline, where she won her first senior title by taking the European Long course race. 1998 finished with a fourth-place finish in Brussels.
