Just to update, since starting this thread my little girl is now 5 months old and growing fast.
We’re in a nice routine with her but my time for cycling has become much more sporadic thanks mostly to me being away for work 2-3 days a week and staying in hotels which don’t have gyms/bikes.
My wife is very understanding and although she would let me go train when I am home I’d much rather spend time with her and our children at the moment.
Thankfully this will not be my long term working pattern so things will improve on the training front but I’m not overly upset as I’m not training towards a particular goal this year. Things should pick up in the summer though.
