These past four weeks have been relatively active as I have gotten back in to running, and cycling. Still haven't made it to the pool, but I am really more interested in getting stronger on the run, and certainly on the bike.
Most of my runs have been during my lunch hour at work. That means treadmill running for as many quality minutes as I can squeeze in. I've been ramping up the time on the treadmill instead of focusing on mileage because the treadmill sucks and I mileage just isn't the same as on the road.
This makes ramping up the running duration and intensity fairly easy. Since I am only dealing with minutes, I can do 35 minutes on my easy days and 45-50 minutes on the harder days. Those harder days include intervals, hills, and anything else I can think of to make things interesting.
Best of all, I get a good workout and can stretch, shower, and walk back down the hall in about an hour. It is a nice way keep active during my busy schedule at home and work.
