running ouside the corniche won't be at all fun.. actually it's unusual to see people walking in the streets here in Doha ..lot's of streets don't even have side walks and the pavements don't have space for people to walk on ...wearing shorts and sleeveless t-shirt is ok specially with the nice warm winter we have here ... u can wear anything u want it's ok...UNLESS Thomas u r a hot girl then u'll be in big trouble ;)
