  9.2.3 Realis - reality

The Realis is used when reality strikes. The probability that the condition set will materialise is quite high or better is considered high by the one speaking.

If he runs 20 miles his feet will hurt.
If you read a lot you are wise.

In English both sentences are in indicativo (the reality mode), using the present tense or the future. In Spanish both sentences are in present indicativo. They just simply state a fact using the si to indicate that there is a slight uncertainty. Still, this uncertainty is not big enough to use subjuntivo and condicional.

Si le da el dinero, le deja en paz.
If he gives her money she will leave him in peace.
Si compra el libro, lo lee.
If he buys the book he reads it.
