you dont need winstrol if you are a distance runner man. Winstrol is a bad choice for any track athlete IMO because it increases your risk for injury. I know some sprinters who have strained their hamstrings and fucked up their knees while on winstrol. EQ or anavar would be a good choice for a power track and field athlete such as a sprinter, or thrower. Test is a bad choice because even with anti-e athletes will still hold water.
winny will make you faster. It will increase your RBC, decrease you recovery, boost your strength and add very little wieght.
Eq will do very little for what you want, but it will decrease recovery time, as will deca. You wont see the strength gains you se from winstrol, and you'll probably gain more weight. Other than not being sore, Eq has little to offer.
