What's My Pace Again?

According to my little pace card, in order to run a marathon in four hours or under I should be running at a pace of nine miles an hour. This counts out to 3:55:58 for a full and 1:58:04 for a half at a pace of 9:00 a mile.

Last Thursday I ran my six mile buddy run in 54 minutes which comes out to a 9:00 a mile pace. Technically this means I can run a marathon in four hours, right? Uh-uh. It means that I can run six miles at that pace and will have to work extremely hard to maintain it for 26.2 miles. So I put my time into my pace chart calculator and this is what it told me.


1600 m 10K (6 miles) Comfortably hard 1/2 Marathon Maintenance Full Marathon
(400m) 1:57 2:15 2:16 2:23 2:30 2:30
(800m) 3:55 4:31 4:33 4:47 5:01 5:00
(1600m) 7:50 9:02 9:07 9:34 10:02 10:01

Half marathon estimated time 2:06:18.
Full marathon estimated time 4:24:25.

This pace chart gives me various running speeds or paces for different distances or interval lengths. Based on my fitness level and six mile time I should slow down for my longer runs. If I start out running at a nine minute pace I will quickly tire out and eventually slow down at the end. By starting out at a slow pace and maintaining it through out the long run I'll be able to achieve a great time.

For kicks and giggles I decided to find out how fast my average six miles should be in order to run a full marathon in four hours. Drum roll please! My average pace for six miles should be at a pace of 8:18. A half marathon at a pace of 8:47 and a full at 9:06. That'll lead to a half in 1:55:51 and a full in 4:00:20! I have a lot of work ahead of me if I want to run a full marathon in four hours. That 4:24:25 is looking realistic right now but I'm going to push for a faster time than that. Wish me luck.
