Mo Farah insisted he was completely over his indoor-season wobble after a comfortable win in 28-degree heat in the Bupa London 10,000 on Sunday.
The world 5,000 metres champion was always in complete control but left it until the final 200m to sprint clear and win the 10 kilometres road race in 29 minutes 21 seconds.
The time was nothing to write home about, but victory extended the 29-year-old's winning streak to three races at the start of the Olympic outdoor season after an indoor campaign in which he looked tired and missed out on a medal at the World Indoors in Istanbul.
Farah proved any concerns of fatigue were misplaced were a superb 1,500m-5,000m double in California nine days ago, winning over the longer distance just 55 minutes after running the shorter - while wearing trainers rather than spikes and when he was just meant to be pace-making.
"My aim wasn't to try to finish it, but I ended up finishing it which is a good indication things are going well," he said.
"The indoors is done now, we forget about it and move on. It was a nice way to start the outdoor season. It's a big year and I'm looking forward to it.
"I love the outdoor season, I look forward to it every year. I had a great year last year (winning gold over 5,000m and silver over 10,000m at the World Championships) so I want to be able to repeat that but do even better.
"The indoor season was really disappointing, but you know as an athlete you've got to move on. That happens and my plans were always for the outdoor season rather than the indoor."
Farah appeared to toy with the field for much of today's race before kicking 200m out - as had been the pre-race plan, he said afterwards - to cross the line ahead of Japanese marathon runner Arata Fujiwara.
Scott Overall, the former shoe salesman who will run the marathon for Britain at the Olympics, was third home in 29mins 26secs.
Farah said: "I am definitely pleased with the run. My main aim was to come out and win it, rather than worry about the time. And I did that.
"I've just got to stay injury-free, stay focused, it's not long to go now.
"Training's going well, I've done a good block so it's going in the right direction. Things are going well and to plan."
The United States-based athlete, whose next outing is over 5,000m at the Diamond League meeting in Eugene on Saturday, admitted it was good to test himself in such warm conditions.
He added: "You've just got to get used to the conditions, it could be rainy or really hot (at the Games), so you just make sure you prepare well.
"The heat can affect you a lot, but everybody has to deal with it. As long as you can get well used to it at training camps it's okay. We'll prepare for all kinds of weather."
Overall was happy with his run after only arriving in the country from Flagstaff, Arizona 24 hours earlier.
"This kick-starts my marathon preparations. It was good to test my fitness over 10km. I feel I am strong but need to get faster," he said.
Mara Yamauchi won the women's race in 32m 52s as she also steps up her preparations for the Olympic marathon.
This was a valuable chance for her and Overall to get a good feel for the course, with today's race following closely the Olympic marathon loop.
And both feel it could throw up some surprises.
Overall said: "It's a course that's full of twist and turns. You need to watch the corners, if you get 20 runners bunched together in an Olympics it could get a bit hairy."
Yamauchi added: "It's a bit unpredictable, levels everybody out a bit. It's quite challenging. You might get a few surprises.
"Anything that slows down the really fast people is a leveller and you might get one or two of the not-so-fast athletes like myself coming through and springing surprises, hopefully."
