I’m facing the situation with equanimity and I’m not sure if this signifies a new maturity and perspective or suggests I don’t care as much as I used to about my running goals. As a dedicated over-analyser, the fact that I don’t have the energy for such navel gazing right now is a clear sign that I’m not fully recovered. For the moment, it simply feels good to be upright again.
The day before the virus struck, I ran 9 miles, 6 of them a tad faster than marathon pace. It felt unreasonably hard, and I should have suspected something was amiss. The next morning – Saturday – it was too late to cancel my coaching duties and I muddled through two hour-long sessions before heading home and climbing straight into bed, fully clothed and shivering. When I woke up, feverish, late in the night, I still had a stopwatch and whistle around my neck.
I didn’t get back out of bed again until the following Saturday and it took me a further two days to put on my running shoes to see if I had anything to give. Not much, it turned out. But two miles is better than being stationary and whatever panic my mind conjures up about how little time I have left and that 20-miler I missed on Sunday, my body knows that it needs to ease back in gently, deadline or no deadline.
I’m thankful to my dear Garmin for notifying me at regular intervals that I am DETRAINING. No shit, Sherlock! But the scientific research makes for dispiriting reading. Studies suggest that fitness declines are sharpest in the first 12-14 days of inactivity, levelling off thereafter. One study of trained athletes found that levels of enzymes associated with endurance performance halved in 12 days, while VO2 max dropped by 7%. Another study showed a rapid reduction in blood volume, a lowering of lactate threshold and a greater reliance on carbohydrate metabolism (instead of fat). But on the brighter side, the research suggests it doesn’t take as long to regain recently-lost fitness attributes as it did to earn them in the first place.
I just have to hope I still have time to make the start line at Brighton.
