Just moved to Huntington Beach - fill me in on tri scene!

Welcome! Tons of triathletes in the area. Great race going on this weekend...pacific coast tri. Where did you move here from? Bike: Typically I will head south from HB since that's where the hills are. Pretty flat in HB and Long Beach. Run: depends what you are looking for. Killer hills and trail running at el morro state park. Nice flat but pretty loop (10 miles) in Newport at the Back bay nature reserve. Great group of triathletes meet for a ride at Bonita creek park on Saturdays at 730am. That is about a 10 min drive from HB (off the 73 and University)

Hello and Welcome to HB. HB has been my home for the last 24 years.
Like Anne-Marie stated there are lotsa Triathletes in the area.
I train alone for the most part but there is a local club called OC-Tri Club. I see them at various races.
We have a decent mix of training profiles here. The Santa Ana River trail is a flat, non-stop 30 mile one way trail that starts at PCH and ends at Green River Drive in Corona.
Head into Newport Coast for some decent climbing and from HB into Irvine to Lake Forest for some rolling hills (Santiago Canyon).
Swimming choices are pretty wide open. Corona Del Mar is a common place for triathlete as is Belmont Shore, in Long Beach.
Running is the same as biking. Hit the Beach Boardwalk for flats and Newport Coast for hills.
If want more options send me a PM and I will give you my number and can tell you what I know.
And for races look at TRIFIND.COM there are races for each state on that site.

sportyj from AZ?   You may remember walking with me at IMAZ in 2008, i remember that like it was yesterday.  I am a little north in Torrance, but we get down to Seal Beach - about half way between - and ride the San Gabriel River trail to the dam and back, about 60 miles. 

Also check out Tri-Zone, in Los Alamitos. They have weekly rides on Saturdays, a great group of people. They also have a group that rides from various locations on Sundays as well, and a Wednesday evening spin class (bring your own bike & trainer, if you have one).

On the weekend head out to Bayshore in Long Beach in the early morning. You'll meet loads of triathletes swimming out there at sun up.
There are a lot of local clubs Tribe of Long Beach, OC Tri club plus a lot of smaller clubs as well.
For rides you can stay flat by the coast or for hills head north to Glendora Mountain Road. If you want to stay in OC check out Santiago Canyon area.
In OC I can only think of two tri specific shops, Tri Zone in Los Al, and One Tri in Irvine, lots of great bike shops though.
Outspoken in HB is a great group.
Open water swimming check out Corona Del Mar off Marguerite and PCH or Bayshore in LB.
