As you get fitter, training sessions where you do two legs together (a brick) will help you increase your endurance and get used to switching from one sport to the next. While riding after swimming isn’t too bad, running after riding can take a little getting used to.

A couple weeks before the tri, do a couple ride - run sessions. Go for a 20 minute ride, hop off the bike and go for a 15-20 minute run. When you run, start slowly and loosen your legs. When you feel good, you can pick up the pace a little.

This is also a great opportunity to practice your transition. If you are able (depends on the location), lay your gear out ready for the run. Ride in, hop off your bike and push it in, change into running gear and go.
