Here, ようだ means something like it seems, it appears, or it looks like.
So 散歩コースは長いようだ means the speaker is making an inference, not stating a hard fact with full certainty.
It has a softer nuance than just saying:
- 散歩コースは長い。 = The walking route is long.
With ようだ, it becomes more like:
- The walking route seems long.
- It looks like the walking route is long.
This is often used when the speaker is judging from some evidence, impression, or available information.
In ようだ, the だ is part of the grammar pattern.
You can think of よう as a noun-like word, and だ is the plain form of the copula attached to it. So ようだ works as a set expression meaning seems to be or appears to be.
Even though the sentence already has the adjective 長い, you still use だ because it belongs to ようだ, not to 長い.
Compare:
- 長い = is long
- 長いようだ = seems to be long
In polite style, this becomes:
- 散歩コースは長いようです。
