If you have a transportation of your own, the way to Losail Intl Circuit is thru corniche, then west bay going to Al Khor. It is on the left side going to Al Khor. Yes it is not an F1 race track, but recently GP2 and speedcar was held on that track. I think on 12-14 of March there will also be super bike (SBK) race, I just dont know the exact time of the race.
