Tuesday and today, I had the pleasure of having my girlfriend ride her bicycle next to me while I ran. Yesterday, it worked, but my legs hurt. I didn't have a chance to warmup. I only ran 2 miles, though, so it wasn't all that bad.
Today, I had my long run day. Keep in mind that I primarily run 5k's, so my long days are 5 to 7 miles. I ran 4 miles before heading back by home and picked up my girlfriend on her bike. I was already well warmed up and ready to go the same speed as her cycling. Again, keep in mind that she isn't cycling like Lance Armstrong. I wish I could run that fast. Doesn't everyone though. We did just over 2 miles together and today, she kept giving me motivation to keep pace. She was saying things like, "Keep those knees up" and "you got this." I didn't ask her to do it, which made it so much better. She's such a great person. It was like having a coach and not having to pay for one.
In the end, I ran much faster than I have previously during my long runs.
