I ran it last year and it was perfect for running 
Was very chilly early in the morning, a few degrees above freezing I think, there was a few frosty nights when we were there. It was clear though, so as the sun made an appearance the temp climbs very quickly (compared to UK) I remember going to the start in shorts n t-shirt feeling very cold, but once underway, it was great.
Like as has been said, try to stay on UK time, I deliberately went only a few days before and got up n had breakfast at 3am over there (a cosy 8am in UK) Then once the race was done, switched to later starts for the remaining time.
