For automotive sports high g (5+) turns are pretty normal there is a good reason why F1 drivers loose like 10 lbs during a race it’s an extremely taxing activity you need to be in insanely good shape and condition your body to be able to withstand those forces for the 1.5-2 hours of a race.

It is an extremely taxing activity, but the weight loss is mostly water.
It’s sweat, I’m not sure how much sweat marathon runners sweat out during a race, especially since many of them dehydrate before the race to lose some weight but I wouldn’t also bet on a marathon being more taxing than an F1 race its both are very hard activities as driving a formula car takes a lot of strength.
