I got to the bike path and headed North towards Will Rodgers Beach (about 4m.) The sand was crazy! I was getting my newly shaven legs sandblasted! Before I knew it there were spoonfuls of sand in my shoes...but I carried on. For whatever reason I was determined not to walk. I wanted to see how far I could go! The best I've done in that department is a half marathon. I turned around when I reached Temescal (at WR Beach) and had a glorious tail wind. I definitely felt like I was gliding, but my knees had had it.
I made it about a mile or so up Ocean Park (hilly) when I felt myself falling apart. I made it up a few hills, but on the way down felt as though my knees (both!) were about to give out. I decided to pull the plug once I stopped running - I could barely walk to the market across the street! Luckily my wife was more than willing to pick me up...3.5 miles shy of my 18 miles...DAMN! FAIL!
On the upside, I don't think I injured myself besides overdoing it...and I know I can run 14.5 miles continuously keeping a pace of around 9:40 with my HR at about 160 bpm average. But I'll be putting in 3.5 miles early tomorrow morning...as if that'll make the difference. :)
