EVIAN RESORT GOLF CLUB, France — Lottie Woad battled not just the undulating slopes of the picturesque Amundi Evian Championship course to take an outright lead, but the weather too.Temperatures soared to 90 degrees Fahrenheit on Friday as Woad, the fourth-best player in the world, hit eight birdies to go 11-under-par and one shot clear of Aki Awai. Woad, who is from Farnham, England, had to top up her Leeds United-embellished water bottle at almost every hole.And while the 22-year-old might have the lead to herself for the first time at a major tournament, one thing she was not alone in on Friday was her constant use of a sun-blocking umbrella and plenty of SPF.“You just don’t really get much breeze,” Woad said. “That’s the thing that makes it hot. The fairways are OK. Just the tee boxes are quite stuffy.”Iwai let a 5-shot lead slip with an unhelpful double bogey on No. 6, her 15th hole of the day after starting on the back nine. The 24-year-old stayed under an umbrella throughout her round, stepping out only for tee shots.Jacques Bungert, vice president of the tournament, says the refillable stations on tee boxes have already been used five times more than they were at the same stage last year. In between players teeing off, constant golf buggies are whizzing up and down the hills delivering giant Evian bottles to each hole.Water from Evian’s famous bottling plant is put through a filtration system and used at the golf resort. To replenish the greens, head greenkeeper Adrien Petrocelli and his 60-strong staff were here in the early hours of the morning watering the short grass just as golfers with early tee-off times were arriving.Jeeno Thitikul, who is in fifth place at 6-under-par, described the greens as “weird” and “bumpy” after her second round. Thitikul, the second-best player in the world behind only Nelly Korda (who missed the cut), was at the course just before 6am and watched ground staff watering the grass, which surprised her given it was so close to players taking to the course.
