Swimmers
Although the least common path into multisport, a background in swimming offers you a good bank of strengths and abilities that you can use to transfer to your future in multisport.
As swimming is your strength you will be able to maintain your ability on fewer sessions per week. Try reducing your swims to two per week, while adding in two or three bike sessions and at least three, short run sessions per week.
Monday | Running: 45mins fartlek |
Tuesday | Swim: 60mins Spin class: 45mins |
Wednesday | Running: steady 30mins |
Thursday | Rest |
Friday | Bike: 60mins turbo/rollers, focus on high cadence and smooth pedals |
Saturday | Swim: 60mins Running: 40min hill reps |
Sunday | Long bike ride: 2hrs steady with hill sections |
Cyclists
Cycling is possibly the hardest of the three disciplines from which to move into tri. But the different kinds of cycling will all bring their strengths with them, so the type you’ve been involved in can make a difference
To adjust your regular routine, cycling can be reduced to two or three shorter sessions a week, with one spin class or similar. Swim and run sessions should start as short and frequent, then increase as you progress.
Monday | Rest |
Tuesday | Swim: 30mins technique Run: 30-40min fartlek |
Wednesday | Bike:Â 45min spin class |
Thursday | Swim: 60mins aerobic endurance/technique |
Friday | Run:Â 30-40mins steady |
Saturday | Bike: 2hr long ride |
Sunday | Swim: 45mins technique Run: 45min hilly run |
Runners
Many runners head to triathlon after being frustrated with injury. The move across is therefore a popular one, as it allows you to retain your competitive spirit, while at the same time easing the pressure on your body.
To go from runner to triathlete, keep your running ticking over, but invest time in swimming regularly to maximise the technique gain. Work on your bike pedalling technique and spend time just enjoying being out there riding.
Monday | Swim: 60min aerobic endurance/ technique |
Tuesday | Rest |
Wednesday | Swim: 30mins technique Run:Â 60min intervals |
Thursday | Bike: 60min turbo or rollers, working on cadence and pedalling |
Friday | Run: 45mins steady |
Saturday | Swim:30mins technique Bike: 90min hilly ride |
Sunday | Bike:Â 2hrs long ride, steady, with 15min run off bike |
