The race's longest stage saw a 208km trek which started and finished in Sur. Again, it came down to a sprint finish and it was Tuesday's opening stage winner Theo Boss who was first over the line with Daniele Bennati in second and HTC Highroad's Matt Goss in third.
That third place for Goss was enough to keep him in the leaders jersey.
Stage Four is 157km long and is from Sultan Qaboos University - Jabal al Akhdhar (Green Mountain).
