Interval Workout

Most cyclists think the only way to do training intervals is inside on their trainer.  That's not so.  You can do intervals outside as long as you find a road/path where you have time/distance to perform a steady-state interval effort.  That is, a road/path void of any stops.  I have just that path/road.  It's a canal/tow path near my home that runs adjacent to the Delaware River.  It's flat, and at night, it's deserted.  The only slow downs are 2-5 second slow downs for road crossings and/or bridge crossings.  In the interval workout last night, I completed two intervals at L3/L4 (sweetspot) zones: the first being 25 minutes long and the 2nd being 45 minutes long.  Each interval was separated by a 5 min. rest.  The rest interval was when I dismounted my bike and walked across a Delaware River bridge (on the walking path).  At the end of the 45 minute interval there was a 10' cooldown period  Here's the workout:

5' Warmup
5' RI (Rest Interval)
10' cooldown

Here's what it looks like graphically:

What I really like about this graph is the W' curve (red line).  It shows how my stress went from positive to negative during the interval workout.  They (experts) say when your W' equals zero that you're nearly out of gas.  That was true last night.  In fact, I was running on fumes at the end of the 1st interval.  The second interval was no different...running on fumes at the end of the interval.  You can see how the 5' Rest Interval (RI) re-charged my batteries but that they were drained shortly thereafter- again.  No doubt a good interval workout that stressed the legs.  My legs were sore when I got home last night.  In fact, they're still a little sore this a.m.  Now, I need to get some rest and recover so the leg muscles can rebuild (stronger) and get ready for the next effort/workout on Sunday.  Until then.  Power ON!  Coach Rob
