Is it time to throw in the double threshold towel.

Lol wait so you ramped your mileage from 16-65? Then started running 80 mile weeks?

After a 3 week layoff?

Yeah your double threshold runs way too fast or you probably weren't ready to handle that type of training yet. Usually when people are breaking their femur they have to work for it.

It also sounds like you ramped up your training way too fast when you were a little bit out of shape from the stress reaction time off. Why did you ramp your training up so fast and why did you start doing double threshold at all until you got in a couple months of solid training? Double threshold doesn't work immediately it takes years sometimes to develop. I would suggest not doing it at all or doing it the correct way.

Grasshopper must feel his Kung Fu, not force it.

I went from 16 miles to 83 in 7 weeks. Was running 80 mile weeks throughout cross season. I follow my lactate meter (running at my aerobic and anaerobic threshold levels) even when i’m slightly above the desired values I stop the session or slow it down.

this is what happens when YouTube

Look better. You have successfully achieved injury and illness; only overtraining remains.

You didn't do anything resembling the double threshold system as it's intended, you did moron training that happened to include some double threshold days. The result of this foolish of training off such a short build-up is actually pretty good all things considered.

Take a break from the double threshold and just get used to running a lot + running 2x day for a while with a couple single threshold days and some sort of X factor workout. Patiently rebuild fundamental fitness before moving to any extreme approaches.

Lol in 7 weeks??? After a layoff??? Come on man. Not only dude you ramp up your mileage you started DT too. Good god.

Wtf? It was a 3 week lay off, not 6 months. Of course you can get back to your normal milage in 7 weeks.

Seems aggressive coming back from the stress reaction.

It looks like you're doing 6 hard workouts/week? That's aggressive. Either do the 2 double T sessions/week or do 1 with the track workout. Give your body a chance to recover. How are you structuring the double T sessions? It's easy to get carried away and not run them at true T. I would scale but & train smarter not harder. I also wouldn't read into the 16:05 versus 15:28. Maybe your body hasn't adjusted to the hard workouts. Maybe you're fatigued. Maybe you're still getting fitness back since you had recent time off. 16:05 is your current fitness. Can you improve from there?

Switch to the successful Dancan method by the Swedish JS.Will make you faster than ever.Only single thresholds.

Damn, this autocorrect.

I meant to say, switch to the unsuccessful Dancan method by the Swedish JS.Will make you slower than ever.Only single thresholds.

A tale as old as time - give a runner an idea and he'll find a way to kill himself with it.

Decided too not throw in the towel trusted ran 4:01 1500 with very little work at that pace (just double threshold) should be able to easily run under 15. Thank you guys for fueling the fire.

Seems like a little bit of healthy internet criticism can be good after all...?

Nice job.

Wait. Did the Internet help you? And even more surprising, LetsRun did. Guys after 20 years of activity we have finally benefitted someone. In all seriousness congrats on the 4:01.

So what did your training look like leading up to the 4:01? Just mileage and two double threshold days?

It sounds like your training program in general is too aggressive and it's not just the double thresholds. Cutting those would be one thing that could help you recover, but not the only ave to improvement.

I did 2 days of double threshold and one day of hills (2x10x200) jog back. Ended the base in early may block with a road 5k in tornado conditions (to end the block) I ran 15:45 (beat guys with pb in 14:45) after this I started introducing some 1500 paced workouts and some vo2 max sessions with one double threshold day a week and keeping the mileage relatively high (10-20% less the base). I was racing almost every week so those were like the specfic sessions to sharpen up. A week looked like this.
June 6 - 10km easy
June 7 - Am: 12km easy, Am: 12km easy
June 8 - Am: 4 x 6 mins, Pm: 7xk + 10 x 200 walk/jog
June 9 - 20km easy run
June 10 - Am: 8km easy, Pm: 8km easy + 4 x 100 fast
June 11 - Am: 5 x 6mins, Pm: 25x400 r:30”
June 12 - Am: 6km easy run, Pm: 6km easy run
June 13 - Am: 6km easy + Pre race, Pm: rest
June 14 - Am: 10 min shakeout, Pm: Race 1500 (ran 4:01). Racing this Friday believe I can run 3:56 the 4:01 was pretty easy and was comfy. Thank you everyone for your feedback!
