Hi when i go out for a ride and that is not very often i get fed up, the reason is up until 1992 i would ride at least 40 miles a day, Club runs every sunday, i was skinny so hills,Mountains were my forte, i would occasionally get dropped on the flat but as soon as the road went up i was back on the front......well in 92 kids and a wife came along,the bike dropped down the list of prioritys until eventually i stopped, last couple of years i have been back out on the bike but what really winds me up is i really struggle uphills to the point where i get off and push...if i persevere will fitness come back or is that it for me....the legs are still skinny but a little weight as been put on in the usual places.
