Hello, first post, so please forgive my lack of forum familiarity/vernacular.

I have a Haro V2 with all original parts and I am beginning to train for triathlons. I plan to compete in a couple of sprints at least, this year. Not really positioned financially to purchase a new bike, nor do I think it prudent given the novelty of my interest.

I would like to change a few parts of the bike so I can make use of it during competition:
Fork (Rigid) [Can anybody tell me the dimensions of the fork on it (•RST CAPA T6 75mm) or recommend a compatible replacement? Thing won't lock and I think I lose a lot of energy to it.]
Seat [Any recommendations ideal for distance?]
Tires [I assume road tires of some sort?]
Pedals [This is a maybe, but if someone can tell me a solid direction to go I will do it]

Any other parts it makes sense to upgrade/replace?

Thank you very much for helping with this. I just want to train and compete without buying a new bike or dropping large sums into the one I have.
