For sure. Choose the club to suit your needs. Racing or touring.. If they race and you don't , you will lag behind and get discouraged.. Choose one that supports your goals... It took me about 2 months to condition my legs before I'd consider climbing...
Don't think you'll be ready to increase your miles drastically . Take them up gradually...
..A club member took much of the winter off. He had been pretty fit before winter struck.. Busy with a soccer team , his winter sport , so he missed many club rides.. So we went on a metric century last Sunday...
All the riding he's missed.. He cramped four times. One cramp was so painful, looked like he was going to die.. you can loose your fitness in no time, if you start missing out on your bike routine..
