150s on turf / tests

Did a brief tempo workout 3x150m, then ran a hard 150m, all on turf.   400m fitness isn't quite there, and I have to decide tomorrow if I'm going to race Sunday.   

Not where I would like to be.  Even after 3 days off from running, still feel a slight amount of pain til I get warmed up.  

Stretches, drills, bands, 50m strides

Hoka rocket x2s on

3 x 150m on turf w/ 30 sec rest - 23.50, 24.17, 25.07

PT balance and strength exercises

150m on turf - 21.64

I was going to do 4 x 150m, faster, but these were too fast to complete 4X at my fitness level.  I bailed about halfway into #4.  My HR was in the mid 170s when I started rep #4, and a minute after while I was walking back, peaked at 185.  After another minute it was down to 137.  

I did some balance and strength exercises then ran a 150m at near race pace.  It felt pretty good, but I knew I wouldn't be able to survive 400m.

I'm going to see what it feels like tomorrow and if it doesn't swell or get stiff, go to the gym tomorrow night and do some starts.  If OK, I'll go.  Not expecting much.  

I am close to race weight, was 139.4 lbs after workout, but I ate a big dinner.

Doing the balance and strength exercises, I was struck at how much more difficult these were to do with my R surgical leg, not only because it's weaker, but because my L leg is dominant.  Try these exercises with both legs, you'll see what I mean.  Most people have a dominant leg.  Still a slight amount of knee pain when I do these.  Arthritis.  

Balance and strength exercises.  Try these with your non-dominant leg.  Not so easy.

Blood tests:

My latest blood work showed an alarming result. My CA19-9 level was well high (78) over the normal, which indicates, along with the imaging and family history (grandmother), a susceptibility to possible pancreatic or GI cancer. All this requires careful surveillance and retesting. The test result could have been spurious and influenced by a slightly high glucose (103) and some gastric distress (diarrhea).  It could even be something like heavy tea consumption, as one test correlated.  That certainly fits me!  Will certainly retest in a month.  Maybe get an MRI w/ contrast.  Fortunately, my liver enzymes AST/ALT are back to relative normal (22, 28).  So, I may start the collagen and glucosamine supplements. My knee was feeling better when I was on them. It was probably the niacin that caused the liver issue. 

No need to panic.  The Mayo Clinic says:  

Carbohydrate antigen 19-9 (CA 19-9) is neither specific nor sensitive enough to be used as a cancer screen.  Serum CA 19-9 levels should not be interpreted as absolute evidence of the presence or absence of malignant disease.
