Great Britain take a 51-strong squad to the World Athletics Championships in Helsinki, which starts on Saturday.
Many experts are downbeat about the team's chances of returning with many medals, but BBC Sport has picked out six who might make waves in Finland.
Radcliffe insists she is not looking for redemption after her disastrous Olympics last year when she failed to finish the marathon and the 10,000m.
But the 31-year-old will again tackle both events as she continues her quest for a first major championship title.
Since the Olympics, Radcliffe has bounced back with victories at the New York and London Marathons.
Her recent form has ensured she will start favourite for the longer event, which is scheduled for a week after the 10,000m.
Welshman Benjamin shot into 400m medal contention with a storming run at the London Grand Prix on 23 July.
The 23-year-old broke 45 seconds for the first time as he stunned a strong field, including Olympic champion Jeremy Wariner.
His shock win came just four months after he was taken to hospital when a routine injection left him with a spinal fluid leak.
Now, Benjamin heads to Helsinki as the eighth fastest in the world this year.
Triple jump legend Jonathan Edwards believes 22-year-old Douglas can be a medal contender in Helsinki.
His endorsement came after Douglas leapt 17.64m to triumph at the AAAs in Manchester and overhaul Edwards' own long-standing record at the event.
Douglas, the 1999 English Schools champion, broke 17m for the first time in his opening competition outing of this season.
He is world-ranked third this year behind Marian Oprea and Jadel Gregorio.
Following Denise Lewis' retirement, Sotherton will be Britain's lone representative in the heptathlon.
Olympic champion Carolina Kluft is the overwhelming favourite to take gold, but 28-year-old Sotherton should not be too far behind.
The Isle-of-Wight-born athlete took bronze in Athens last year and finished second to Kluft in Austria in March, setting a new personal best.
Sotherton began the year by taking silver in the European Indoors.
Sprinter Devonish goes to Helsinki determined to shed his reputation as merely a relay runner.
The 29-year-old was part of Britain's Olympic gold-winning 4x100m team and won World relay silver in 2003.
But this season he has shone over both 200m and 100m and is hopeful of adding to his individual medal tally of European and Commonwealth bronze.
Devonish has a season's best of 20.41secs in the 200m and 10.19secs over the shorter sprint.
Williams, the son of Welsh rugby legend JJ, is one of Britain's most promising athletes.
The 21-year-old made a successful late bid for Britain's World Championships team thanks to some sizzling form.
He set three personal bests before taking European U-23 gold in 49.60secs, despite stumbling at the final hurdle.
Williams was Welsh U-16 100m backstroke champion and a member of the Welsh U-16 rugby squad before choosing athletics.
