Hi,
I'm in the position now where I have a little more time to train. I'm wondering how best to use that time. Currently I run 5 x week, about an hour at a time, maximum 90 minutes once a week.It's all off road and about 500m average a day. I get a couple of gym sessions in during the week where I'll do a 30 minute interval session on a bike plus resistance training and/or a circuits session.

I now have another few hours free but still unable to get out running for more than 90 minutes. What would be the best way to boost my fitness. My goals are to develop more endurance as I tend to do AM AL races. Should I do more bike work, I don't like treadmills, or should I just get out and run more-I can do two 60 minute sessions a day?

Any advice appreciated, I'm 47 and trying to hold back the ?inevitable decline.

Neil
