interval training at the cost of long runs?

I've been running for a year and usually run 25-30 MPW. Lately I've made a lot of progress on my long runs, dropping the pace from about 10:05 or so to 9:30. At first I thought I was just having a good day, but I've been at that pace for some weeks now. I've also upped my MPW to 35-40.

I've got a 10k on June 8th that I want to PR (54:04), maybe even break the 52 min mark (8:30 pace, although that's a stretch at best). I'm on the second week of RW Ultimate 10k Training Plan. Although I'm a novice runer, I am following the advanced program which has two interval sessions per week. I'm setting my sights high, so I do the intervals at a pace that targets an 8:30 race pace.

This week, I struggled on my long run of 10 miles to keep a 9:40 pace. Two questions:

First, can I assume that the long run struggles are a result of two interval sessions in a single week?

Second, Would easing up a bit on my long runs to a 9:40 pace hurt my chances of a PR as long as I do the interval training well?

Re: interval training at the cost of long runs?

Two interval session are a lot in a week, especially for a modest mileage runner.  No doubt that will cause you to struggle on a long run.

Your long run pace is still only 10k pace +1:10. That is still pretty fast. You could go much slower and still gain fitness from these runs.

Re: interval training at the cost of long runs?

Don't time your pace on your long run, it's basic endurance ... and it will probably be a little slower since your body is more tired from the extra interval work ...

I can't remember which sources but I've read in a number of books/sites that you should keep similar workouts (endurance, basic speed, VO2Max) 3-4 days apart for maximum benefit and avoiding overtraining ... this allows body to recover and adapt to the specific energy system improvements you are training for ... and you also need to alternate hard and easy days; so don't do your LR the very next day after an interval session, or if you do, take 2 easier days directly afterward ... that's been the general concensus on the information I've found on the topic ...


I haven't seen the RW workouts but I followed a Pfitz-based program loosely and it called for a LR and LR2 (2/3 distance of LR, approx) along with a VO2Max or Tempo paced run and then a basic speed workout each week ... So endurance and basic speed occured every week and VO2Max or Lactate threshold occured mostly on alternate weeks or sometimes in different phases of the build-up to the race (LT near the beginning of the training schedule and VO2Max near the peak performance) ... I saw steady improvements and also increased my distance of race over the summer and ended with a marathon in October following this type of set-up - never dropping the speed workouts even when heading to the marathon ... racing every 2-3 weeks for the most part ... 5Ks - 10Ks -15K-10 miler- some more 10Ks - 20 miler - marathon ....

that's how my experience went and I hope you have similar success with your training ... it's sounds good to me and just make sure to space those harder workouts and let yourself run slower if need be on those LRs!

Happy Running!!!

Slow down for the interval session on Thursday.  Then you should be fully recovered for the Saturday long run.

Re: interval training at the cost of long runs?

Personally, for a runner of your background I would recommend only 1 interval session ( at just a little faster than race pace ) a week and more mileage throughout the week. Improving your aerobic ability is the key to getting faster in any race from 5k on up.

As for the pace, I think that's a function of the amount you are running, lower mileage runners will naturally run a little faster ( relatively speaking ) on their daily runs because they won't have the same accumulated fatigue as higher mileage folks. That said, increasing your mileage and taking it a little slower will help your aerobic ability more than running faster and less.

Re: interval training at the cost of long runs?

I hate to tell you but on your low mileage, your training may be counterproductive. I know, I trained like you and did fine but it wasn't until I slowed down some of my runs and cut back a lot of my fast intervals is when I got faster because I got more aerobicially fit. Your training is too fast and too much fast for your miles. You need to base your training pace off of your current level of fitness not your goals. A 5K race can help determine your training paces or your upcoming 10K.

If you are adamant about running your long runs faster, then you have to ditch one of those interval sessions (Thur). Because with 2 interval sessions, you have to do your long runs at least 1:30 slower than 10K pace and preferably closer to 2:00 slower. You will be all torn up and not strong for your race at your current training method.

Now, one other solution is to ditch the Thurs interval session and run EZ. On Saturday, within your long run, finish the last few miles at 9 min pace progressing to 8:30 pace the last mile and then do some striders.

Re: interval training at the cost of long runs?

sorry to add this but not only is that schedule counter-productive, it's just begging for an injury (or several)...

Re: interval training at the cost of long runs?

you should pick up a pfitzinger or daniels book on training for running, they do a great job of explaining what speeds to run specific workouts for the maximum benefit.  surprisingly the best speed for a particular workout IS NOT always the fastest speed...

Running fast in daily work outs is "racing". Save your racing for "the race". When you race in training, your progress will ultimately halt and you will become stale, burnt out and most likely injured. You are putting out hard efforts several times per week without the aerobic base to support it.

Think of the analagy of weight lifting. Lets say you want to get stronger in your bench press. Would you work your chest to the max most days of the week. NO! You would not absorb the training and grow from it, just continue to break down. Most power lifter work their chest hard once and maybe twice per week and recover the other days and get stronger during these days. Recovery is the key to success.

Re: interval training at the cost of long runs?

I run most (90%) of my training runs at 9:00-10:00 per mile pace.

A few days ago I ran a 5k at 6:34 per mile pace.

I will agree that:
You are running way too fast in training.

Re: interval training at the cost of long runs?

The reason the advanced schedule has two workouts a week is that they have assumed as an advanced runner you have put in the kind of base mileage necessary to handle that volume of quality work.
The long run at a decent pace has its purpose.  I like a staged run where you run different paces for each block of mileage.  Some call this a progression run.  But the long steady run has a purpose to.

Ok, so how does this sound:

Saturday: 12 mile long run
Sunday: off
Monday 5-7 recovery
Tuesday: 7-9 mile with 4-7 at tempo pace
Wednesday: off
Thursday: 7 miles
Friday: 5-7 miles


 



My thoughts:

5-7 miles 'recovery' runs, too long for your recovery runs at your pace. Keep these within 40 minutes.

Tuesday, if you find the tempo portion too demanding or you're running that tempo pace too slow, reduce the tempo portion to 3-4 miles, the rest of it is warmup/cooldown.

Friday, limit to 5 miles.

toss some strides into the thursday run, it'll help with leg speed.

edit: for tempo pace, refer to McMillan's calculator[/URL" target="_blank">, it looks like you should do it somewhere between 8:30ish and 9:00 minute pace if you're targetting a 52 minute 10k.
