Tonight, Running Planet tells me "...a slight, whole body, forward lean will enlist the help of gravity just enough to assist with directing your momentum smoothly forward. Keep your hips pressed forward and your butt tucked in." Check. At least my form is correct. It also says that, "...studies have estimated that outside air resistance creates an increase in your workload between 2% and 10%, depending upon your running speed." So, apparently I'm performing between 2% and 10% less on a treadmill?
Well, what I did tonight was something that Frankie taught us last week at Run Club. Sprints. Last week, I thought I was going to ...die. We ran 1 mile to the track, then we ran 4 laps as fast as we could, with a 2 minute break in between each lap. I came in as one of the 1st girls for each sprint! To be honest though, I only ran 3 laps since I felt entirely too nauseous and dizzy to attempt the 4th. Wouldn't want to be that girl - vomiting on the track in front of 100 people that you only see once a week! But I digress. So, tonight I ran 10 minutes at a steady 6.4mph then alternated between an 8.0mph sprint and the steady 6.4mph at 1-minute intervals for the next 10 minutes. So I was only up there for 20 minutes, but like Frankie said, "If you want to get faster and faster in the long runs, you gotta do the sprints." So here I am. I'm a-sprintin'.
In my immediate research of a few other websites, the seemingly obvious difference between treadmill and outdoor running comes down to the fact that on a treadmill you will have:
- Decreased wind resistance (unless... what? the fan is blowing on you...?)
- Assistance via the propelling belt
- No terrain changes
Best part about tonight? One night away from Nike South Beach Run Club on Thursday nights!
