Cycling training: a road bike plan and winter indoor training

Where to start

Cycling training is built around regular easy rides, a long ride and measured doses of harder work. At base level, start with three manageable sessions, separating demanding days with rest; in winter, some work can move indoors. The plan below is a guideline shaped by your current workload, terrain and goal.

1trAIner is an AI coach that builds cycling sessions around your route and schedule, reviews workload using watch data and adjusts the week to what you actually complete.

Five zones: heart rate and power, road and winter indoor riding

Zone 1 — recovery

Very easy, without strain. Heart rate is low relative to your cycling zones; with a power meter, use recovery power.

Zone 2 — endurance

Full-sentence conversation at a steady easy effort. Most volume belongs here, including winter base work on an indoor trainer.

Winter indoor training plan

Zone 3 — tempo

Breathing is noticeably harder and conversation shorter. Add tempo blocks after adapting to an easy training week.

Zone 4 — threshold

Hard but controlled, in limited intervals. Set heart-rate and power boundaries separately; one scale is not an exact conversion of the other.

Zone 5 — high intensity

Short hard repeats for prepared riders. Heart rate lags, so do not accelerate to chase a number; use perceived effort and power if a meter is available.

Weekly structure

Easy and recovery rides form the basis of the week: ride at a conversational effort.
Intervals or tempo work: one key session after building a base; a virtual race replaces that session.
Long ride: easy, gradually extending duration while practising fuelling and bike handling.
Rest between demanding days. Do not combine missed sessions into a single day.

Sample plan

Numbers are guidelines, not mandatory targets. Start with a manageable workload and increase one variable at a time. Do not push through pain; reduce the load.

Week	Focus	Sessions per week	Key session	Volume
1	Consistency	3	Easy long ride: 60 min	About 2 h per week
2	Extend easy work	3	Long ride: 75 min	About 2.5 h per week
3	Effort control	3	3 × 5 min moderate, with 5 min easy between	About 2.5 h per week
4	Lighter week	3	Easy rides only	About 2 h per week
5	Consolidation	3	Repeat your familiar week 3	About 2.5 h per week
6	Endurance	3	Easy long ride up to 90 min, depending on how you feel	About 3 h per week

How AI adapts your plan

The AI coach compares duration, distance, heart rate and completed volume from connected watches with your plan. Report terrain, fatigue and any move indoors: virtual kilometres do not equal outdoor kilometres, and the same route can require different effort.

Frequently asked questions

How do I build a road cycling training plan?

Start with available days and manageable duration. Keep easy rides and a long ride, then add one interval session; account for terrain and handling skills.

How do I train on a gym bike or indoor trainer?

Use a warm-up, a timed main set and a cool-down. Provide ventilation, a fan and drinks; indoor riding supports your base but does not replace road-handling skills.

How much cycling should I do each week?

The example uses three sessions totalling about two to three hours. Start lower if that exceeds your usual workload; extend duration once the week feels manageable.

Which heart-rate and power zones should I use?

Use cycling zones rather than automatically copying running zones. Without a power meter, use heart rate and perceived effort; allow for heart-rate lag on short intervals.

Can indoor training replace road riding in winter?

Easy work and intervals can be done indoors. In spring, rebuild braking, cornering and group-riding skills separately, without increasing every demand at once.
