In casual American English, "She set a goal to run a 5k race within three months" sounds like "shee SEHT uh GOHL tuh RUHN uh FAHYV-KAY RAYS wuh-DHIHN THREE MUHNTHS". Several things happen here, and the headline one is the Flap T Across Words: the T at the end of one word flaps into the vowel that starts the next. Keep stressed words long, unstressed words short, and link the consonants forward into the vowels.

What makes this sentence sound American.
The "t" at the end of "set" links to the vowel starting "a" — it flaps to sound like a quick "d", with the tongue briefly tapping the ridge behind the upper teeth. This is called the Flap T Across Words, how Americans glue words together so they sound like one phrase. It comes out as SEHT.

Common pronunciation mistakes in American English.
The textbook way isn't wrong — it's just not how anyone actually says it.
Treating every L the same.
The L in "goal" is a dark L — the back of the tongue rises toward the soft palate, adding a small "uh" quality before the L. Dark L adds a small schwa-like "uh" before the L. The back of the tongue lifts toward the soft palate.
Hard T at the end of a word, not a flap.
The "t" at the end of "" links to the vowel starting "" — it flaps to sound like a quick "d", with the tongue briefly tapping the ridge behind the upper teeth. Same flap as within-word (R1) but spanning two words.
Pausing between the words.
The "" at the end of "" flows directly into the vowel starting "" — the consonant migrates to the next word with no pause between. Final consonant "migrates" to next word — no pause between.
Pronouncing the function word too fully.
"she" is a function word — in connected speech, the full vowel reduces to a quick "" sound and consonants may simplify. Full vowel reduces to schwa /ə/ or other weak vowel. Consonants may simplify.
