Jayjay,
Welcome! I loved hearing about your 'competitive' thinking - and getting back on a bike will make it come back to you, and it' s a great motivator! Especially when , after time, you start passing other riders after having everyone pass you! (I'm just getting to that point!) I love the feeling of being 'all that' when I get out on my bike. At least I am, compared to my invisible, polite, middle-aged mild mannered school teacher persona. ON a bike I transform into a bad-a** dynamo in lycra, racing young male roadies out of stop lights after riding 60+ miles!
It's a joy to ride a bike!
