I'm sure with some interval training you'll improve pretty quickly - think back to when you first started and what a shock to the system it was and remember how great it felt to drop minutes off your times!
Hey thats nothing, did my first 10 mile TT after a break of 36 years, was 7 minutes slower than my best teen time 26-10secs, but now got the bug, but not sure a skin suit suits a mid 50,s guy !!!!!!!!!!!!!!, then again if the girls like it.
