What's my training "style"?

One Christmas break, my mom and sister helped me shop for jewelry, makeup, and accessorries, none of which I wore much of beforehand. When I went back to work, a lovely Chinese coworker who was still working on understanding our language and culture said to me, "Before, you have no style. Now, you have style. Don't go back". Now that I'm all set with my unique"style" of my clothing and makeup, I'd like to find my unique training "style" to help me improve running performance and decrease my injury risk.

I've been thinking a lot about training "style" lately, especially since my training partners and my "life partner" have been doing a whole lot of volume as they train for a marathon, whereas my masters rowes and I have decreased volume to accommodate lifestyle and injury recovery issues...and both my masters rowers and training buddies have been getting faster. I wonder what style is right for me?

I've been grappling for some time with what my personal optimal traning volume is. I tend to want to do more, more, more to get better, better, better. It always seems to work for a little while....and then injuries creep up. With 3 major injuries and 0 pr's in the past year, it seems an appropriate time to develop a new philosophy.

My old training schedule looked something like this:
1. Run 7 days, with 1 intense workout, 1 long run, and maybe a double here and there to add up to at least 60 and sometimes up to 80 miles.
2. cross train on 2-3 days, sometimes lifting, sometimes biking, sometimes rowing, sometimes swimming.
Total volume: 10-14 hours
Best times during this training: 5k 18:31, 10k: 38:31, 10 mile: 1:04:37, 1/2 marathon 1:23:21, marathon: 2:59:25

My new training schedule for the fall is much different. It includes more variety and less volume. It seems to make perfect sense to me for my rowing goals this fall, but it will be interesting to see how it translates to running:
1. Run 4 days per week with 2 8-10 mile runs, 1 hard run, 1 long run to equal around 40 miles.
2. Row 3-4 days per week with 1 steady state row, 1 hard workout, and either another tempo workout or a race(s).
3. lift 2-3 days per week (heavy, structured lifting).
4. 1 day off every 2'ish weeks
Total volume: 8-11 hours

I want to try to race at least a 5k and 10k, and maybe a 10 miler and half late this fall just to experiment with how the change in training translates to change in running times. Am I wasting time running so much and constantly facing injury and illness? Or, do I really need to run more miles (and how many more?) to race faster? I am truly starting to believe optimal volume is different for everyone. Optimal style (xt versus all running; amount of intensity) is different for everyone.

I keep running in to the same brick wall with my training. Time to try something new!
