I'd love to get my marathon time into the 2:3X range or under. Do some gravel races and cyclocross races to keep things interesting.


I live in Michigan with my wife, Megan. I started running in September 2010.

Megan's Complex Gym - 10 miles steady w/ 2 miles at 9.5. Lost my data but most of the run was 160-170 BPM.

Fought the 4.5 mph cool down feature the last 10 minutes to get my 70 minutes in.

Flight delays for 4 hours or so then canceled flight last night. I'm flexible so I was only mad I wasn't back here to spend time with Megan sooner.

I've learned a few things about living here. 1) The water pitcher is insufficient. I've been drinking around 150+ oz a day and I keep 2 gallon pitchers running most of the time 2) the max 10.9 mph governed treadmills just aren't going to work.

Way to get the miles in Jason. Not fun to fight the equipment. Maybe a screwdriver and YouTube to get around the governor? ;)

Jason what's your max HR? Just curious where those numbers put you at a heart rate reserve percentage.

From Jason D on Tue, Feb 11, 2014 at 12:12:29 from

I am guessing they aren't pre-programmed, Matt, so that sounds like a great idea!

Bret: I wish I knew. Calculators suggest as high as 191-195, but that is probably vomit effort. My resting heart rate is 40-43 usually. I would say it is actually lower as some other formulas suggest (185-186). When I start hitting 180+ I working on end of race pace as I did on Saturday's workout when I was hitting 179-182. Another 5 or 6 minutes would have wasted a race effort. I am still sore and I rarely am so I am guessing I got some buildup in the legs.

I think 164-165 is cruising marathon effort (just guessing by feel) and pushing maybe 170 at the very end.

This day's run was 162 average with a max of 178. Generally I like to stay in the 145-158 range and only approach 160 at the end, but I had to push to get the miles in with the shutoff.

Ok so if you are 28 or 29 years old - 192 makes sense.

HRR (Heart Rate Reserve) Effort to stay aerobic should not exceed about 80%. Here's the formula in case you don't already have it: = MaxHR - Resting HR *__% + RHR = Target BPM.

192-43 * 70% + 43 = 147.3 (70% HRR effort or 1/2 effort according to Lydiard)

85% HRR would put you right at 170 BPM to stay aerobic. Anything over 170 is anaerobic.

If the effort for the run is easy/aerobic - 145-155 is the right zone to be in - and looks like that's where you are.

From Jason D on Tue, Feb 11, 2014 at 16:45:34 from

Thanks for doing the math. I like that this takes into account resting heart rate given that I could be 39/40 to as much as 45-47.

After I got back from injury I started using the HR monitor. I don't put too much into it, but I think it is very beneficial for easy runs (and workouts on the treadmill). If you are at 150-155 in the first few minutes you will be too high (probably) by the end of the run.
