Thats a pretty awesome climb up a hill!
I keep telling my partner I need a specific commuting bike - probably a steel road race one - with panniers and "carry-stuff" facilities... and this is a perfect example of why!
I'd simply fly up hills if I had to carry all that extra weight in my training!

Glad you were able to balance and rebalance everything and not lose anything along the way.

Just gonna repeat myself again - AWESOME ride home up that hill!
