Iím trying to help a friend lose weight (his main problem is motivation, so Iím there as motivation) and at the same time make up for the lack of riding time Iíve had during the week recently. Heís thinking 2 miles of mild running every night (except weekends) but I donít think Iíll be satisfied with that, so Iím shooting for maybe 5-10 a day. Will this running cause undesired effects in my pedaling, power, endurance, etc? or will the extra workouts for my legs be beneficial? Not to say I'm going to screw over my friend if it's not great for me, but at the same time I'd just like to have a better picture of where it will take me.
