Well I'm a tourist from cold wet green Britain, but I visited cousins there half a dozen times - usually in the summer - and it never stopped me enjoying a morning run. I admit I enjoyed the swim after (a.m.) or cold beers (p.m.). And if you're doing track work, those warm muscles make you fly doing your 200s in the grass.
But it did kind of freak me out that we had to take a hosepipe and water the concrete patio for 30 minutes before it was safe to walk out there and barbecue...
