Are you thinking about starting racing? Ask about future events in here, find out what you can expect at them and who else is going so you can scrounge a lift off someone rather than riding the 30 miles to get there yourself!
As a former Rider B (in my dreams), it was instilled in me by my coach that "The only time it matters to be at the front is as you cross the line. Anything earlier than this is just showing off."
