BORDERS middle distance athletes Guy Learmonth and Chris O'Hare are set to take on the world.

Learmonth will line up in this weekend's heats of the 800 metres at the IAAF World Championships in London.

The 25-year-old from Berwickshire finished second at the British Championships last month.

And he followed up his success by clocking a new PB of 1.45.77 just a week later at the Muller Anniversary Games.

Guy goes into the Championships with the 65th fastest time in the world this year - but gritty determination and excellent racing skills has seen him regularly punch above his weight, most notably at the Glasgow Commonwealth Games, where he finished sixth in the final.

Following Saturday's heats at 12.45pm, the qualifiers will return to the London track for the semi-finals on Sunday evening with the final scheduled for Tuesday at 9.35pm.

Chris O'Hare's chances of success in the 1500 metres, which begins next Thursday, look significantly better on paper as he has the 16th fastest time this year.

The 26 year-old from West Linton has already won bronze medals at the European outdoor and indoor championships.

And he has also reached the final at previous World Championships and Commonwealth Games.

Chris marked his return to the UK in July from his adopted home of Boston with an emphatic victory at the British Championships.

He followed up his British title by out-sprinting several big names to win the Muller Anniversary Games the following week.

And he then smashed John Robson's Scottish record from 1979 with a time of 3.33.61 when finishing seventh in the Monaco Diamond League.

Following the heats of the 1500 metres, which begin on Thursday at 8.25pm, the qualifiers return to the track for the semi-finals next Friday at 8.10pm.

And the final is scheduled for next Sunday at 8.30pm.

Chris and Guy are among a record 16 Scots who will compete for Team GB & NI at the IAAF World Championships.

Hurdler Eilidh Doyle captains the British team which also features distance athletes Laura Muir, Beth Potter, Steph Twell and Eilish McColgan.

Zoey Clark will contest both the 400 metres and 4 x 400 metres relay, and Callum Hawkins goes in the marathon.

Josh Kerr and Jake Wightman line up with Chris in the 1500 metres.

And Lynsey Sharp will be hoping to progress in the 800 metres.

Lennie Waite has also been selected for the 3000 metres steeplechase and Nick Percy competes in the discus.

The London 2017 World Champs begin on Friday.
