Blown out Legs

I took a Ryde at Hammer House this morning.  I love these bikes--you really do get a CORE workout and it is also good for shoulders and arms.  I wanted to run 4 after--I have run immediately after Spin before, but I had some errands to run and when I got home, I got caught up with work related "stuff".  

So I did not head out for my run until hours later--but my legs felt "blown" anyway.  So heavy--like lead--but no pain.  I muscled though and got the four done and despite some walking my pace was pretty decent.

For all the triathletes out there--I give you a lot of credit.  I don't know how you do it.
