Toronto: Ride/run/swim suggestions

So, are you staying downtown? Do you have access to a car?

For biking:

From my perspective as a westender - the easiest if you have a bike and are relatively close to the waterfront is to go to the Martin Goodman trail and head west. It will take you pretty far but you'll eventually connect with Lakeshore Blvd. which is pretty bike friendly (traffic can be fast but the earlier the better) and you can stay on that for quite some time.  I am sure that on Strava or Map My Bike you can see where people typically go.  (I have a route this way and i can describe more if you want since there is some construction in Mississauga right now)

If you have a car a very popular thing to do is 'ride Warden'.  It's a country road just north of the city - there's a baseball diamond where most people park (Just of hwy 404 at Elgin Mills) - you have to head east on your bike on Elgin Mills for a few minutes and then go left on Warden and you can basically ride north right to Lake Simcoe.  Just turn around when you've reached the time.

Swimming

Lots of options too - tons of public pools with an hour or two each day for lane swim. Costs $3-3.50 - search lane swimming on the city of toronto website. it's not the greatest site, you'll probably want to use a map to see the nearest to you.

Also open water in Lake Ontario - see here: http://oannesswims.com/ they have group open water. And C3 (a coaching group) outside of the city has open water times in a quarry for about $10.  But it's out of the way if you don't have a car.  You can get to the Cherry beach for swimming by bus if you want.

These are ones I know of. 

Running:

Toronto has lots of great places to run - just depends on where you are for specifics.  If you want a group or to ask about routes near you there are tons of Running Room stores.  (Are you canadian? You might know this so sorry if it is a repeat) But they have free group runs on Wednesday at 6:30 and Sundays at 8:30am. If you are downtown there are several stores.

Is that a start? I may be able to help more depending on where you stay. 

To Jen's point - it really matters where you are going to be staying.  But there should be lots of options available to you no matter what.

Yonge and Lawrence is a lovely area.  (I lived around there for a while - near the Glendon Campus of York but before i became a runner/triathlete).   For running you'll be well set up being near to Sunnybrook and the Beltline.  You'll also be handy to the Yonge/Eglinton running room where they can help you out with more routes.

I don't bike around there - i know there are well-traveled routes around Bayview but you might need some other folks to chime in.  There is the Trek store midtown - my swim coach sometimes leads bike groups and seminars from there. And Gears is in Leaside and is great bike shop - you may be able to get better info about biking in the area and groups to join.
