Learn Russian: Это очень сложный маршрут, мы не доберёмся туда быстро. - This is a very difficult route, we will not get there quickly.

The dictionary form is добраться (to get to, to reach). It is a perfective verb, which means it focuses on the result or completion of an action. When you conjugate perfective verbs with present-tense endings, they actually form the future tense. That is why it translates to "we will get" instead of "we are getting".

Why does the sentence use туда instead of там for "there"?

Russian has different words for "there" depending on whether motion is involved. You use там when talking about a fixed location (being there). You use туда when talking about motion toward a destination (going there). Because the verb involves travelling to a place, we must use the directional word туда.

маршрут is a masculine noun. Why does the sentence start with the neuter word Это instead of Этот?

When you use the word simply to mean "This is..." or "That is..." to introduce something, you always use the fixed neuter form Это, regardless of the noun's gender. You would only use the masculine Этот if you were attaching it directly to the noun as an adjective, like in the phrase этот сложный маршрут (this difficult route).

This lesson covers the dative preposition по. How would we add it to this sentence to say "along this route"?
