I am 46, in good shape, and am attracted to training for triathalons. However, I have two considerations:

1.My age - and keep in mind I know nothing about how triathalons are structured. Are there age groups? If so how broad are the age groups (within 10 years, five years, etc.)

2. I don't know if this is going to be a deal breaker for me, but I have bunions on both feet. I am not in pain, but will the running just send my bunions around the bend? I cycle and I am a good swimmer. I used to be into running big time, but it dropped off after university. I am going to ask my doctor about this. Anyone have to deal with bunions and running?

3. Assuming that my bunions don't keep me from participating, what is a good way to break into triathalons? Where did you begin?

Any help is appreciated.
