pit stop in sprint race ???

if it's happen, what different between sprint race and feature race ??? that's look same...

When I first heard this it didn't make sense either, to stop and make it a longer race doesn't make it a "sprint", but as always lets see how it works in Zandvoort, wish I was going again

I guess when they stop in the "sprint" there is a tyre change, not very "Think Greener Racing" with another set of rubber boots to make and dispose of. If it makes for good entertaining racing I guess I can live with it    

I don't agree pit stop in Sprint Race, because it can make the race not sprint.

But, I believe that the pit stop can be better in entertaiment.
