I've recently started running again and trying to bring down my times for long distance runs. I did a half marathon in 1hr 59mins, what kind of training do you guys recommend to bring down my times to about 1hr 40mins mark.
So far my routine is just to run 5 kms each second day at an average pace of just under 5mins a km. Then on the weekend do a run of 10kms. The routine definitely needs work, what do you guys recommend?
