Have only had a chance to do the one shake down last month. This was basically shortly after i got back on the bike after 6 weeks off due to broken collar bone.
It was hard going, definitely felt the rolling resistance! Felt great going over bigger rocks and gnarlier sections, looser sections etc, but on the hard pack flats and uphills, definitely felt hefty.
my lack in fitness probably also made it worse than it normally would have been!
