What your blood says about your triathlon.
Ferritin and transferrin saturation
Swimming, cycling and running in one week ask a lot of iron. The saturation says whether supply keeps up with your volume, ferritin whether the store is still there.
hsCRP and haemoglobin
After a block with three sports your inflammation value sits higher. With haemoglobin and ferritin you read whether you recover or just carry on.
Energy balance and hormones
Long hours and a low race weight push testosterone and thyroid down. You see that in the blood months before form drops.
Triathlon test
Twelve values for people who combine three sports. The full iron picture, haemoglobin, CRP, vitamin D, TSH and the hormones that show your energy balance. No cholesterol, no blood sugar.
