Recovery

Sleep and recovery for people training twice a day

Training is the stimulus; recovery is where you improve. How sleep, rest days and daily habits decide whether hard hybrid training makes you fitter.

Training makes you tired. Recovery makes you fitter. If you train hard but do not recover well, you will not improve as much — and you are more likely to get injured. Sleep is the most important part of recovery.

Why sleep matters

During sleep, your body repairs muscle and restores energy. Poor sleep is linked to worse performance, slower recovery and a higher injury risk. Most adults need seven to nine hours a night; people training hard often feel better at the upper end.

Sleep habits

  • Consistent times: go to bed and wake at similar times each day.
  • Dark, cool room.
  • Screens off before bed where you can.
  • Caffeine: avoid it in the afternoon and evening. See caffeine before a race.
  • Late training: very hard sessions late in the evening can make it harder to sleep for some people.

Training twice a day

If you train twice a day, recovery matters even more.

  • Eat and drink between sessions.
  • Make the second session easier, or a different type.
  • Sleep well.

Rest days

At least one full rest day a week. Light activity — walking, easy cycling — is fine.
