TM training

I think I've mentioned before that I'm signed up to participate in Tough Mudder this fall.
So, I've stepped up my workout and training in the past couple weeks/months in preparation for it.
I downloaded their suggested workout from the website and realized, I'm wayy under par on the physical demands required for that particular workout routine.

It's broken up into 3, 10 minute "circuits" which is a routine that involves both cardio and strength/weigh training at the same time.
It was quite discouraging. So I talked with a friend of mine who participated last fall, and is part of our team this year as well. She suggested doing my own "circuit" workout. Do my regular strength/weight training and in between each exercise run for 2 minutes.

So, today being Monday, I've decided to start this week's workouts this way.
Today I was able to run my usual 3 miles broken up into 2 minutes at a time AND still get in a whole strength workout at the same time. Finishing in about 45 minutes (usually takes 30 including rests to do just the workout without any cardio). Since I know I rested less in between workouts than normal. I feel like I got a better, faster, harder workout in this afternoon than normal. But I didn't feel as wiped out, exhausted, and discouraged as I did by trying the 45 minutes of TM circuit workout.

In a weird way, I feel like I'm cheating - why can I run and lift weights at the same time and still feel ok, but can't do the easiest level of Tough Mudder training??
Oh well! At least I made it to the gym today. Feel like I got a very good, high intensity workout in and did a bit more than my normal! That in my book is improvement.... even if it is cheating.
