i havent done that race specifically but i have raced in sweden, i (perhaps naively)expected sweden, famous for snow. to be cool in the spring, (may race) but it was 91F, hottest race ive ever done,
took me and the event organisers by surprise. water stations were not at all ready for it, still, i enjoyed the race and the country, take plenty of money, sweden is far from cheap. especially food and drink, its like £10+ a drink in most bars/restaurants.
Good luck with your race.
