@Himanshu....
Yes that is what i also do....5 kms 4 times a week....what is my focused timing for the event is less than 45 mnts....already am doing 50 & 51 not very consistently.....i mean at times 50 and sometime 51....focusing not to put on weight at any cost, may be looking at loosing a kg or 2.....
BELOW IS MY STRATEGY FOR THE SAME.....
* I do at least 100 kms of cycling per week [basically cross-training]....
* I do skipping twice a week for building my endurance, strong abs/hips/ankle and for speed....
* Focusing on building my upper body to do SINGLE HAND push-ups....
* Most important of all is HIIT [High Intensity Interval Training] for building my speed, as of now once a week...by March will start doing Twice a week....
* What is that i wanted incorporate here as of now which i am not able to do is running a Half Marathon every fortnight [for burning fat]....[am also not completely convinced about its advantage as for as recording best timing in a 10k run....]
This is what i do Himanshu as of now....looking at the results....i may make some changes.....i appreciate ur sharing...!!!
