It was a great race for me.I am very surprised to achieve such a fast time. It was very hard mentally to race the 400m without hurdles,” Bol said. "I am so proud to achieve the double. I will never do the double again. Well, maybe. Never say never,” she quipped.Warholm had in 2018 won the hurdles and finished last in the 400, and last weekend had told Bol "I wish you good luck ... You’re going to need it” in reference to the gruelling multi-race challenge.He came to Munich off seventh place at last month’s world championships in the wake of a hamstring injury but was untroubled in the final he won in a championship record 47.12 seconds.Frenchman Wilfried Happio took silver in 48.56 and Turkey’s Yasmani Copello of Turkey got bronze after 2016 gold and 2018 silver."This means everything for me.
