Biking helps running. Running does not help biking. Bugs lets see, he is warmed up and has a faster bike. Yea you would have a hard time keeping up. If you are in much better shape, you can keep up on a lesser bike. But if you are about equally trained, it's hard to keep up. It is kind of like a corvette vs a mini van. You have have the same engine, but if the gearing is different, it makes a huge difference. Also position on the bike is huge. If has curved handlebars or aerobars, and your bike has staight handlebars. he can bend lower on the bike and get less wind resistance. That can make a difference of two miles per hour or more. Clipless shoes and pedals will make another 2 miles per hour difference over someone pedaling in running shoes. Road bike vs mountain bike for me is about 3 miles per hour.
