I'm finally feeling sure that I am making good progress. Yesterday I did 5K easy, and today I did 8K easy. My legs hurt a bit today in that weird way, starting at 3.5K, but only a little - and it didn't hinder me from a decent time of 49:25 for 8K (6:10/km) with average HR of 149. Garmin data here.
Better yet, my legs only hurt a little bit today at work, even though I spent a good hour sitting at the microscope doing injections, and another hour sitting in a seminar. I feel fully recovered this evening, and in fact, I'd like to walk tomorrow, assuming the forecast snow dump doesn't stop me. I might just go ahead and walk at the field house on the indoor track. We'll see.
I'm really excited that I'm feeling better - finally! Too bad there's a huge storm coming tonight and winter is really here. No matter. I'm happy to be feeling decent at last. Not to say there won't be any more setbacks or problems, because after all I am still not sure what the problem was other than B12 deficiency (for sure) and protein deficiency (undiagnosed - possible not certain).
In other news, I have taken off a few pounds, weighing in at 158.6 this morning, which is the first time I've been under 160 in about a month (or so...not sure). That's not great, since my goal WW weight is 155, but it's progress toward recapturing my goal. Racing weight is lower still, but let's take baby steps toward that. I'll get back there - just have to get in the swing of training again, and continue being more disciplined with my eating.
