Indoor training - click here to enlarge

Indoor training means setting up your bike on a trainer and riding without moving anywhere. 

You can use a fancy digital trainer with an app like Zwift which allows you to do virtual training rides and races against other people. 

You can also use a cheaper trainer where you just set the resistance level and ride at whatever level of intensity you want. 

Jona has a few different trainers, many thanks to the well stocked SHC cycling shed:

  • Elite Suito-T smart trainer
  • Elite Arion smart rollers (especially handy for track bikes)
  • Tacx boost cycle trainer (good for wet weather at races)
  • LeMond Fitness Revolution trainer (see a review)
  • A basic static trainer

Indoor training is really handy when you're working on achieving / sustaining particular power output levels. 

Jona would also say it's a good idea when the weather is bad, but dad like the way Irish cycling legend Shawn Kelly thinks.
