Temporary failure of nerve or loss of confidence can happen in any sport. The young British tennis player Emma Raducanu was sailing through Wimbledon, had the hopes of the nation suddenly piled on her shoulders, then, for the first time in the competition, she lost a set. Things weren't going well in the next set, she suddenly felt overwhelmed and she lost her nerve and withdrew. She was honest about what happened to her. I get that. She is very inexperienced at that level and she'll be back. Our young BMX rider Charlotte Worthington overcame a big crashout in her first run to come back in her second run and execute perfectly the almost impossible trick that had eluded her in the first run. No failure of nerve there.
