(and now for something completely different…)
I’m 45, and I’ve had the following results this year:
3mi/16mi/3mi duathlon: 9th overall, 2nd 40-49
2mi/300yd (run/swim): 9th overall, 1st 40-49
3mi/20mi/2mi duathlon: 19th overall, 1st 45-49
500yd/12mi/4mi (triathlon): 9th overall (top 10 got overall awards)
.5mi/14mi/5K (triathlon): 26th overall, 5th 45-49
This was after 6 years out of multi-sport racing, having done mainly bike racing (and lots of hill riding). I started running again last fall, and never put in more than about 18 miles/week running, with the “long” run about 5 miles. Started swimming again (my former strength) this winter, and usually did about 1600yds, 2-3 times per week (longest pool swim in 7 years was this morning with 2600yds!). Max bike mileage was under 150mi/week.
When I trained this year, it was usually pretty hard. I might do 4 miles on a treadmill, and descend the miles from 6:30/mile to under 5:30/mile for the last mile. Did a few track workouts, doing 1/2 mile repeats at 2:45 or so. Most runs were on hilly terrain. Swimming was sets of 100yds on 1:30 or 1:20, or 200s on 3:00 or 2:50 (I used to do 10x200 on 2:30, ten years ago), never more than about 1000yds of intervals. Biking was usually a hilly 23-30 mile loop, done as a TT, solo, with occasional longer (usually hilly) solo or group rides thrown in. I think I did three run/bike workouts, and one swim/bike workout this year.
All the hill riding over the past three years (and dropping 30 lbs) gave me a pretty good CV system, and pretty good leg turnover. This showed in my nearing lifetime PRs in some runs (albeit on the treadmill). What I lacked (and it showed as the summer wore on) was maintainable bike power; I attribute this to not doing nearly enough training for my LT (20-40 minute intervals at 90-95% of LT), nor enough long rides.
I’d skip the weights, unless you are already a good technical swimmer and you want to improve that aspect. Use that time to improve your power at LT with a couple of bike workouts. That’s what I am going to focus on this winter. 2x20 minute intervals on the trainer, twice a week, increasing the power every week or two.
Good luck.
