What constitutes performance really? Where does the rubber meet the road to allow one to be fast and enduring?

Well, it's down inside each and every cell where the glucose molecules and the oxygen molecules are utilized to make energy.

Those among us that are gifted to be fast can carry the oxygen and glucose to the cell quickly and efficiently- and once there a plentiful array of enzymes convert them into energy molecules used for swimming, biking and running.

Where can the system stall?

From Jim in Denver:
I have noticed that since it's been cold here I have been cycling very little and my legs are running better than ever. My usual sore calves are feeling good and my speed has really been picking up. I am doing an Ironman in August. Do you think I should keep my cycling to a minimum and target my IM race for a good run with a slower bike? I am 60 years old.
Thanks for your help.

From Dave Scott:
Why slow down on the bike? Come on, you are only 60! The key to a strong bike leg in an Ironman is ...

For several years my base training for a good Ironman season is to begin in winter and go to the mountains for high altitude training.

Starting in November I began. For the first time I climbed to the top of the 4th highest mountain in North America, El Pico de Orizaba, almost 18,000 ft. high. We left home Saturday afternoon and arrived at 11:00 pm to sleep for some hours on the lower part of the mountain at 11,000 ft.

At 2:00 am, we woke up, took our MAP and coffee and started to climb. We did the 7000 feet trek up and down in 8 hours. It was a very good time. Amazingly, Sunday evening I was having dinner at home.

I recently participated in a 3 day Combat - Kickbox training module at Golds Gym. It was a very very intense 27 hours of punching , kata kicking, knife hand blocks, plyometrics, drills, drills, drills over and over - push ups, dips, mat work, oh my gosh - what was I thinking? It was a day BOOT CAMP!!

I was the oldest in the class at 50 years old and proud to say so! I passed the 2 day training modules and was fully recovered by Tuesday.
