Oh dear!! reading some of the above advice would only make me want to stuff the bike right up some ones loud arse. If the weather is rough find domething else to do, ( I find it pointless getting soaked just to prove that you can.) Get down to the gym, do a few long sessions on the weights, get to a spinning class, if the normal music from that does not get you out on the open road nothing will!!, go for a sauna if there is a reasonable one near you, you could even try Taiji (a lot harder than it looks) . The only rule to obey is "Do Something" and eventually you will get back out on the bike but do it on your terms not what some one else thinks is right.
