"We are likely to see highs of around 21C or 22C which would be close to the record". If you think it's not appropriate, don't do it in fancy-dress.
Conditions may be especially hard for fancy-dress runners, including the nearly 100 attempting Guinness World Records dressed in outfits such as a suit of armour, a Paddington Bear costume and ski boots. He said "there's only one way to run and that's mixing it with the guys", but he also described the race as part of a learning process in which the British record was his aim.
"Through my years on the track I was learning and improving step by step and it's the same in the marathon".
The current mark of 2:02:57 is held by compatriot Dennis Kimetto set in Berlin in 2014, surprisingly the only race Kipchoge has ever lost since his debut at the 42km distance in Hamburg in 2013. But he does not understand why Farah made a decision to stay loyal to Salazar's Nike Oregon Project training group until 2017, two years after they started to be investigated by the US Anti-Doping Agency - an investigation that continues.

Kipchoge and Keitany face formidable opponents who will also have their eyes not only on the winners prize of US$ 55,000 (Sh5.56 million) in each race but will also be seeking the US$ 1 million (Sh100 million) that is at stake for the World Marathon Majors jackpot.
He was quick to make clear he was making no suggestion that Farah has done anything wrong, saying: 'I'm not trying to say this is the avenue Mo is taking, or anything, but there is a little taint there.
Jones said he thinks it is a "foregone conclusion" that Farah will break his 1985 record of 2hr 7min 13sec in London on Sunday, and admitted he was "surprised" it hadn't been broken sooner.
