Jessica Ennis-Hill and Katarina Johnson-Thompson got their bids for Olympic heptathlon gold off to flying starts in Rio on Friday.Johnson-Thompson led the field on 2,264 points after two events thanks to a British record clearance -- and equal world heptathlon best -- of 1.98 metres in the high jump. It was some statement of intent from an athlete who was left distraught at last years World Championships in Beijing when three fouls in the long jump dashed her medal hopes.And her team-mate, the defending champion, Ennis-Hill is third, 22 points further back, after clocking 12.84 seconds in the 100m hurdles and then clearing 1.89m.She is only seven points down on her score at the same stage during London 2012.The 30-year-old produced her third-fastest time since those London Games -- and her fastest in a heptathlon since then - before pulling out her best high jump since before the last Olympics.Johnson-Thompson, the heir to her compatriots multi-eventing throne, had clocked 13.48secs over the hurdles, 0.11 down on her best this year, but a solid enough time given the rainy conditions at the start of the morning.Their battle is already shaping up to be one of the showdowns of the Games, provided it goes all the way to the 800m -- the last of the seven events.Belgiums Nafissatou Thiam, who also cleared 1.98m, is second, 10 points ahead of Ennis-Hill, who is out to become the first British woman to retain an Olympic title in athletics, two years after the birth of her son Reggie.Canadas world number one Brianne Theisen-Eaton lies fifth on 2,151, with two more events, the shot put -- Johnson-Thompsons weakest -- and 200m to come on day one.The Britons were hit by a wall of noise on their first morning of London 2012, a teenage Johnson-Thompson saying Wow at the roar which greeted her introduction.There was no chance of that at a near empty Olympic Stadium for the start of competition here, even if the British fans were the ones making the most noise.There looked to be barely a couple of thousand spectators in the 60,000-capacity venue when the action got under way.

Williams technical director Pat Symonds has become the latest Formula One chief to call for a rethink of team radio restrictions, saying the current system has the potential to breed negligence.Mercedes became the first team to fall foul of the new regulations after the stewards added 10 seconds to Nico Rosbergs race time at the British Grand Prix for a radio call relating to a gearbox issue. The incident has reignited the debate over the radio restrictions, which are designed to prevent engineers from coaching the drivers from the pit wall.Symonds believes the restrictions go too far and says engineers need to be able to warn drivers of potential issues on the car, such as Sergio Perezs brake failure at the Austrian Grand Prix.On the pitwall, we know our rules pretty well -- and normally when something happens, we know what to do, Symonds said. With this, every single race, theres a debate that goes on in the pit lane, oh, we shouldnt do this, what are we going to do?Poor old Perez in Austria, how ridiculous. Youre going to do tens of thousands of pounds worth of damage too the car, because you cant tell a guy his brakes are about to fail? Thats negligent.dddddddddddd. Its not just wrong, its negligent.We have debated the very situation Perez found himself in and we said that if thats the case, well tell the driver to stop, we dont care about a penalty, were not going to risk injuring a driver.Symonds believes the rules need to be revised to allow engineers to talk drivers through some of the more complicated procedures on the car.I dont like it. To me its a team sport and we should work together. If people really do object to us coaching the drivers, I can live with that, but helping them manage the systems? I really dont think thats a problem.But where do you draw the line? Its a team sport and if the driver has to drive the car alone and unaided, should he change his own tyres? Can you imagine that? Where do you draw the line? And where they have drawn the line [on radio communications] is not in a good place. ' ' '
