Hi everyone,

Iam training for my first half marathon, 5weeks into the training for the City to Surf.
Yesterday I was doing one of my long runs (16K) and was wearing my 2xu compression Tights.
The first 4k going at 5:30min Klms my legs started to feel like heavy sandbag, I was starting to feel a bit sore but kept going, after 5km my legs were fine and I have never ran better and never felt more confortable.

Just want some advise why my legs felt that way as this was the first time it has ever happen
I mentioned the tights as I have worn them several times for my long run and wasnt sure if this effected anthing.

Thanks Jass

We were talking about this on a run around the Tan on the weekend. Some very experienced runners put it down to "good days and bad, just keep running". I have had the same experiences on occassion although I've only been running for about a year. Sometimes the old energy system just takes a bit to flush out the cobwebs!

I agree with the good days/bad days theory - sometimes it all comes together, and other times it doesn't. It's not worth over analysing - just stay true to the training program and keep all variables within your control finely-tuned so you minimise the chance of having a "bad day" on race day!

It helps to keep a diary so you can see patterns in your good and bad days - eg sleep/nutrition/weather. You may even have had a big running week with speedwork or hills, and these have a cumulative effect, leaving you "hungover" on an easy run. Sometimes I think I am handling the load well, and then BANG - a supposedly "easy" run is a struggle. I have to tell myself it's no big deal; in fact, if I can come away from a sluggish session having learned something about myself (even if it's that I'm a stubborn b*tch who doesn't give up), then it has been a good run.

Another thing with tired legs is that some programs deliberately create a level of exhaustion, so that you can learn to run when tired. (I dont' know what sort of program you are following). Alternatively, you may be due for a recovery week where mileage drops. In other words, there are many reasons why your legs may be tired and assuming you are otherwise well and not overtraining, it's probably a good thing to continue to run when tired.

Of course, you did say that you picked up after 5km - which is a good sign! Good luck.

I agree with the others.
I explain it to my coach as it feeling like I'm wearing tissue boxes on my feet - heaps fun when I was 6 to slide around all over the place, but feels impossible to lift my legs.

For me, it usually happens after a week of doing lots of speed work, or if I've shaved a lot off my pace. And looking at my logs...I bounce back faster when I just stop if I'm doing a session and I get this feeling. If I try to force myself, I start becoming mentally exhausted too as I force myself to do something that physically feels bad, and it takes me longer because I become unmotivated.

So a session like that would result in me taking the day off, or cross training for a session or 2, at which stage I'm craving to go for a run.

And I don't think the tights would have anything to do with it. My legs do this regardless of what I'm wearing.

Don't be disheartened! Hope you feel better in your next session!

Hi Everyone,

Thank you so much for your feedback.

Now I can go back to training and not worry.

I never realise training for a half marathon is so great and the new things you learn with your body during it aswell

Thanks
Jass

I find my legs are sluggish and heavy after a lot of miles or a long lay off coming back from injury. Usually it's a sure starting sign of overtraining/overreaching and my miles become progressively slower before injury results.

Usually when it's after a long lay off I find that I need to blow the cobwebs out and feel like I am starting over like a beginner. But within 2-3 sessions into running again I find that I have got the snap and the lightness back into the legs and I feel that I can run further and faster with less effort this could be as much as 45 seconds per kilometre. I guess the cardiac energy pathways start to come back very quickly and it is like I haven't stopped training. I have notice my resting heart rate has dropped significantly within a week or two. It has dropped from 55-60 back down to the high 30's to low 40's and my running economy has improved significantlty as I can hold a heart rate whilst doing a tempo run of 155-160bpm without it increasing to higher levels. This allows me to keep the same pace/ rhythmn going without slowing down to a jog or cease running after a minimum benefit time of 20 minutes .

In all due fact I find tempo running up to an hour the most beneficial as you know where you are at with your fitness and I find these runs are the most rewarding metally as with speed work. Which can help you with the extra pace or improvement in running times. I find long jaunts are best for marathoners not looking forIspeed improvement. I also recommend that when you are sore or you running stagnates a few days off training doesn't hurt as I know that injuries hurt the most when you are trying to improve you running
