I am aiming to do half marathon next year and would really like a time of 1:40 - managed 1:48 this year - have been running for 2 years now. I see that you have to do about 7.35 min/mile which I can manage in 10k races at the moment but that is pushing myself. I can't manage that while training on my own. But if I do speedwork, I can do 6.30 min/mile for one min fast/one min slow. I'm not sure what to do to get faster. Should I build up from, say 2 miles at expected half marathon pace and add a mile each week/fortnight or should I try and do the smaller reps - 400 metres/800 metres at a faster pace than half marathon pace, or is it ok to do both. At the moment, work and children allowing, I do a longish run 8-10 miles per week, then a 4-5 mile run twice, try and do the elliptical and then speedwork. Can anyone advise. Thanks

I ran 2 HMs this year fairly successfully (after a lay off of many years) -- it's much too far for me really.
Most of my training was in a gym (which I do not generally condone other than for quality sessions).
[E.g 5 x 1 mile reps on treadmill with 5 x 300m slow jog recovery.]
I reckon 13.5 km/h for your mile & 8.0 km/h for your recovery.
This is a great speed endurance session; help to build both your speed & endurance for the longer (10k+) distances.
If you want to do 1/2 marathons you should do a run at 1/2 marathon pace once every two weeks. Try increasing the distance until you are comfortable running at this pace for 10 miles.
I also think that your long runs should be increased. Good luck!
I did a 10k race then used the mcmillanrunning calculator to predict my 1/2m time from my 10k. i then used it to pace my longer runs (up to 10 miles).
Then on race day after a good taper, speed and endurance will come together.
Mairead - I agree with Big Tim, you really need to increase your long runs. Running under the race distance is fine if you just want to get round, but you need to build extra endurance if you want to go for a time. Believe it or not, long slow runs will increase your ability to sustain a faster pace in a race.
Where spare time is no object then increasing long runs with other sessions is bound to help improve.
However, given Mairead's time constraints (same applies to me) and already good base of 1 longish run & 2 medium runs per week, the additional sessions should be quality speed endurance rather than throwing in the extra miles at a comfortable pace.
IMHO you must feel what it's like to run at a faster pace (more than 1min on /1min off). Rapid improved performance will follow.
I don't like to use the term 'plodding' but if you get use to this then this is all that you will be able to do and sub 1:40 will remain a pipe dream.
400m reps are great for 1500m track events and the like but do not provide the sort of endurance needed for the long distances.
I try and do longer sprint intervals for a half training, I think that they are more beneficial for the longer distance. Say 2k sprints with 90 sec recovery for about 25/30 mins.
I would also do a tempo run once a week, except perhaps on the weeks when you are doing the longer run with alternating miles fast and slow. Say again 25/30 mins just as Aardvark suggests.
I have to say I have not achieved such a good time as yourself but my time is very good for my age group, therefore it is all relative.
Then any other time you have left in the week can be gentle miles to make up the volume if you feel it is necessary. But fit in the quality sessions in addition to the long weekly run before adding quantity.
In my view anything over 10 is a long run anything under is not. but it does depend on your goals.
