Hi Dreadgrub. Welcome to the forum!
You’ll be a bit rusty after 10 years but if you’re a previously seasoned rider I’m sure the summer miles will bring it back to you. Not that formally brushing up on your skills is ever a bad idea. I hear good things about 121 courses and our own @MrsVisor did some with Rapid Training that she wrote about here.
What bike has brought you back from the dark side?
