28K later and i didn’t miss the pack one bit, . i drank noticeably less though, because drinking from a bottle is just more hassle . . .
the pump went in my cavenous shorts pocket, which sits back and side of leg so tht was perfect and not noticeable at all when rinding, the tool and anything heavy went in shorts, because having them in the jersey pockets can pull the front of the jersey up and make it uncomfy . .
back was hardly wet though, which with a pack on, i always get a drenched with sweat back.
Felt faster
I enjoyed it
