Copper Box Arena, Queen Elizabeth Olympic Park, Hackney Wick W. TKO COMPETITION is so fierce in the new Dubois family home even an Olympic hero can get the last pick of the bedrooms.British heavyweight champ Daniel, Olympic youth queen Caroline and rising Repton schoolboy Prince moved into their new Romford house just in time for lockdown.And they have all set up camp under the watchful eye of dad Dave, who somehow copes with cooking for his freakishly talented and hungry kids.Caroline, 19, is taking the sessions while laid-back “Dynamite” Dan prepares for his post-lockdown war with Joe Joyce — which has twice been postponed amid the Covid-19 pandemic.The enforced break is DDD’s first in three whirlwind years that have returned 14 wins, 13 KOs and every possible domestic honour.While 2016 Olympic silver winner Joyce will probably be 35 when they finally meet — hopefully in autumn at The O2 — Dubois will have 12 years on him and been kept fresh by his younger siblings.After another gruelling session, Daniel told SunSport: “Caroline takes the training sessions every day, she enjoys picking the exercises and circuits more than I do.“She has our youngest brother Solomon acting like the teacher’s assistant so there is no slacking.“I wish I was fighting now but I am trying to take any positives there and, apart from spending time with the family, the idea that I can use this break to relax, recover and improve is a good one.“The last three years have been relentless with fights and training camps, even if a fight has only gone two or three rounds, there were weeks of hard sparring in the build-up to those few minutes.Every day I wake up hoping the gyms have reopened and that I can start looking at a fight date.“It can take its toll, I don’t feel that it has on me but I have youth on my side and there are a few big names ahead of me in the queue for a world title shot, so I would rather have this break now than later in my career.“Every day I wake up hoping the gyms have reopened and that I can start looking at a fight date.”Caroline’s last bout, her first as a senior amateur, was an Olympic qualifier win at Stratford’s Copper Box on March 14 — just days before the event was cancelled and the Tokyo Games later postponed.The emphatic victory took her record to 41-0 but it came at a huge cost to the reigning BBC Young Sports Personality of the Year.She said: “When we moved here, because I was boxing at the qualifiers, my brothers and sisters all got first pick of the bedrooms.“It doesn’t matter if you are out representing your country in a fight, we are still all just siblings trying to win at everything at home.“I love it when we train as a family. And to be the best, you have to beat the best".But Dubois will avoid what was considered a tough fight with 35-year-old pro and former five-year WBC champion Delfine Persoon in the semis.A rule change meant paid fighters could compete in Tokyo and Persoon, who was handed a controversial points loss to Taylor in June, was targeting Tokyo.But, moments after Dubois got her win, the Belgian veteran and former policewoman was beaten on points and out of the competition.Meanwhile Frazer Clarke walked through his first Tokyo 2020 qualifier after his opponent’s dreams went down the toilet.Clemente Russo, the 37-year-old Italian veteran who beat Deontay Wilder at the 2008 games to land a silver, pulled out of their super-heavyweight clash after stomach trouble kept him in his hotel room.Clarke, 28, will now be fresh for the next round at East London’s CopperBox having gone through without throwing or shipping a single punch.Gutted Russo wrote on social media: “Hi guys, soon I should have been going to the ring to play the first qualifying match for the Tokyo 2020 Olympics.“Unfortunately and with regret, you won't see me fight today. keepi sister. I think he wants to get me on a pay-as-you-go deal but I don’t like the sound of that.“I might base it on how hard he works, if I am impressed with a session he might get some discount.”At the Canning Town sweatbox Daniel usually trains at, mentor Martin Bowers likes the old-school approach of plenty of running and sparring.So Dubois smiled when he saw Joyce had been using a virtual reality boxing game to help keep himself in shape for their mouthwatering meeting.He said: “I saw that Joe had been using a computer game for some of his training but that stuff doesn’t interest me.“Nothing like that is going to help him cope with what I am going to be bringing to him.If there are no Olympics next year then I will definitely turn over but I do feel, with what everyone around the world is going through and suffering, that it would be great to get the Olympics on.“We like to keep our training old school, the circuits and sessions that we do are ingrained into us, like a part of our DNA.
