"I have learned a lot since I made my marathon debut in London in 2014", he said to reporters on Tuesday, reports Xinhua news agency.
Temperatures are expected to peak during the week, with London basking in the sun today, and Thursday 19 April forecast to be the hottest day of the year so far, with temperatures picking up to 26°C. "I am ready for the race on Sunday".
Cheruiyot confirmed here that she would not return to track races, instead focusing on the marathon before she retires.
"Either way it will be a very warm one with high UV levels for both runners and spectators", they added. If that [world-record pace] is what the guys are doing, why not? "What is more important is my own condition".
Millions of pounds are raised for charity at the London Marathon and we don't want to see the thousands of people who have signed up to run, or their supporters, disrupted. "I'm enjoying my running now more than ever".
While Farah aims to "mix it" with the likes of Wanjiru, Kipchoge and Bekele, he has the British and European records in his sights as well as a top-three finish. The 35-year-old will target Steve Jones's record of 2:07:13, set in 1985, when he takes on the 42.195-kilometre challenge for the second time.
Farah believes he's capable of clocking 2:04 hours or 2:03 hours "in the right race at the right pace" but admitted that his strategy on Sunday may change if the favourites go all-out in the early stages. "I'm looking forward to a good race on Sunday", she said on Wednesday.
Speaking to The Times, Farah said he would take the race "one step at a time".
"I'm still to know which pace which to go through", Keitany said placidly at today's press conference. But at the same time, in my mind since 2014 to now I have learnt a lot more and I understand a lot more.
"After the pacemaker dropped out, I just went alone to the finish line", Keitany told reporters after last year's race. Obviously it's going to be hard. But this year, event director Hugh Brasher is going back to the 2003 format of having male pacers in the women's race, again with the same goal: challenge the absolute world record.
