I had a similar experience out on the road a few months ago that really bolstered my confidence on my bike. I’m a new rider and I was out riding with a group that is slightly faster than me, I have to really push myself to keep up. Well I’m riding with the group and I start to fall behind to the point that I was just going to give up on the ride, at that point a guy I’d never met came along side of me and said “I’ve got your back” and he literally put his hand on my back and pedaled both of us back up to the group. It was a great feeling and I’ve ridden with him since. I hope to encourage someone similarity one day.
