Bermudagrass, bluegrass, fescue, perennial ryegrass, buffalograss. Early classification started by the Greek philosopher Theophrastus who classified all plants into annuals, biennials, and perennials according to life spans, and into herbs, shrubs, and trees according to their growth habits.
Calculate how far you run by timing your workout and comparing it to the pace you set. A treadmill's speed settings typically range in pace from six- to 12-minute miles. Divide the number of minutes that you ran by the per-mile speed to calculate the total distance that you ran. For instance, if you use the treadmill for 60 minutes at a rate of 12 minutes per mile, divide 60 by 12 for a distance of 5 miles. Wear an external tracking device while running on the treadmill to automatically monitor distance if your treadmill is older or doesn't provide accurate speed or distance information.
Once you've confirmed you have adequate floor space, you can focus on the size of your running deck -- the actual moving platform component of your treadmill. If you intend to use the machine for walking and you are of average height, your track should be a least 50 inches long by 16 inches wide. If you'll be jogging or running, you will want more room to stride and move your arms, so a track of at least 55 inches long by 20 inches wide is in order.
