Discussion: 400

Would have been fun to run it with you.

Looks like we are well matched. Maybe we’ll get a chance.

Always nice to find something that helps those aches. Never would have thought it would be speed work.

Good for you for trying this. Sure, there's some risk of injury, but I've found spadework to be more beneficial than anything else for improving aerobic conditioning, stride efficiency (even in the terrain), and, yes, even strengthening and protecting vulnerable muscles and joints. Of course, you will want to work up gradually to longer workouts. Four 400's in 105 will provide more benefit than one 400 at 95.

I log shoveling as well, but I don't think that's what he was doing. :-)

George logs spadework all the time. But I never knew about Phil.

If I were to attempt 4x400 at 105 I fear it might turn into a Bricker set.

Ha. The dictionary my autocorrect is based on doesn't have an entry for 'speedwork' and changes it to 'spadework'. Maybe it's time to turn off the autocorrect before I do my next 24 hour romaine.

Ha...speaking of autocorrect, I had to update my weekend entry when it said I did a four hour romaine.

Phil, it also depends on what you are trying to do. While I could certainly use improved aerobic capacity, what I need most urgently is to stretch and strengthen my legs and back, and running as fast I can safely seems to do some of that.
