Sprawdzenie błędów

Bardzo proszę o korektę. Jestem początkująca i potrzebuję pomocy.

Hello Tobias,
How are you ? I'm fine.Thank you so much for yours last letter. I took part in maraton last week. I must practised a lot of and ate healthy food. Two hours in day I ran with my best friends Bethany and Lisa. After we went to restaurant and ate light dinner. When went day of maraton I'm so excited. I started and ran 5 km. I the middle of maraton I felt big ache in my left leg. I didn't stop ran. It was terrible ache. Fortunately I ran to end. I think organisation this type of competition is very great. A lot of people can spent time on healthy activities with friends and family. In the next month will be second maraton in my city. Maybe can you run with me ? I wait to your answer.
Kisses and hugs, Jane.

After (ale czego? musisz napisac) we went to (przedimek) restaurant and ate (przedimek) light dinner. When 'went' (zle - tutaj masz poszedl - a tu chcesz powiedziec przyszedl) (przedimek) day of (przedimek) 'maraton' (ortog) 'I'm' (nie, zly czas - przeszly) so excited. I started and ran 5 km. IN the middle of (przedimek) maraton I felt (przedimek) big ache in my left leg. I didn't stop 'ran' (zla czesc mowy). It was (przedimek) terrible ache. Fortunately I ran to (przedimek) end.
