Yesterday I got on the dreaded treadmill. I generally will not train on one, but during my last training cycle I discovered that it has one very good use: You can work on running at a specific tempo, since treadmills are set to move at a given tempo!
I finished Wednesday’s Yasso 800’s with an average interval of 3:59… indicating that I can potentially run a marathon in 3 hours 59 minutes. I did some basic math and found this would take a pace of 9:07 per mile, about 6.6 mph.
So, still in my work clothes and thus carrying about 6 extra pounds, I set the treadmill to 6.6 mph and ran that for 30 minutes. I had no trouble physically maintaining pace, but by about 7 minutes in I was (true to form) already losing patience with the treadmill, and by 10 minutes I considered cutting it short at 20, while wanting to stick to the plan and push out 30 minutes.
The key to staying focused and getting 30 minutes done: I imagined being at mile 25 of the marathon, knowing at that point I would be in some pain but definitely very tired and wanting to stop, and knowing that at that point there was no other way to the finish line but to tough it out and run that last 10-12 or so minutes. It would probably feel worse than this moment on the treadmill, and if I couldn’t handle 30 minutes of this crap in a gym then how could I expect to handle 4+ hours and those final miles on race day?
I kept my cadence and ground out the minutes, getting to 30:00 and being able to cool down and shut the machine off.
Despite the lack of outdoor air resistance, I felt like that 30 minutes on the treadmill was harder than running that pace would be outdoors on race day.
- First of all, I was tired after a long workday.
- I was wearing my slacks (with stuff in my pockets), my sweaty t-shirt I couldn’t take off in the gym, and my dress shirt tied around my waist. That’s 6 pounds I won’t carry on race day. Plus the wet shirt and the slightly warm indoor conditions prevented sweat evaporation.
- I’m running in place, with no scenery passing by me to help guide me visually. My only frame of reference is the clock.
- Because the treadmill moves at a set pace, I cannot slow down or speed up as needed to maintain comfort. I didn’t change the dreadmill’s tempo during the run.
So I felt good about the workout, even if I didn’t feel good doing it. The tempo is one I could definitely maintain, and if I can handle it in contained, uncomfortable circumstances, I get the feeling I can handle it on race day.
