Time trial training plan, from 12 weeks
From 12 weeks. Your own threshold and the length of the event decide the work, so a ten minute effort and a forty minute effort are trained differently.
By Arne, founder. Updated
Floors, not fixed lengths. These are the minimums for finishing the event. A more ambitious goal raises them, and a season can run up to 52 weeks.
What the weeks look like
Three weeks from the 12 week time trial plan for a typical athlete with a finishing goal. Your own plan is built from your history, your course and the days you can train, so the sessions, the hours and the split will differ.

What a time trial actually asks of you
A time trial is the purest test in cycling and the least forgiving. No drafting, no wheels to sit on, no tactics to hide behind. The result is the power you can hold for the length of the effort, held in a position you can genuinely keep, paced so the finish is not an apology for the start.
The central adaptation is threshold, the output you can sustain for a long steady effort before fatigue arrives faster than you can clear it. Around it sit three things that decide whether your threshold becomes a time. How long you can stay aerodynamic. Whether the output decays across the effort. Whether you paced it or gambled it.
A ten minute effort and a forty minute effort are different races
Both are called a time trial. They sit at different points on your power curve, and your power curve is personal.
The curve is built from your best efforts across your history rather than from one test day. A short course leans on the part of it above threshold, where the work is holding an output that is uncomfortable from the first minute. A longer course leans on threshold itself, and on how well that output survives as the effort goes on. Same rider, two different builds of work.
The plan reads that curve before it writes a session. What the curve, the efficiency trend and the late-effort fade actually mean is covered in reading your performance charts.
The most aerodynamic position you cannot hold is worthless
Position is a capability, not a fitting appointment you attend once. The only power that counts is the power you make in the position you will race in.
Nymiva does not fit your bike. What the plan does is treat time in position as something that grows, and put the sustained work of the specific weeks in the position the event will be ridden in. A threshold session ridden upright trains threshold. It does not train holding that output with your back flat and your head low for the length of a course.
Pacing is a discipline, and it is trainable
Most time trials are lost in the opening minutes, so the plan rehearses the alternative rather than advising it. Key sessions carry a target range and a stop rule, so you learn the correct effort while it still feels comfortable. Verification then asks whether the session was executed as prescribed, not whether it was finished. Hitting the training load and missing the target counts as a miss.
Why the plan you downloaded does not fit
A fixed plan is a reasonable guess about a rider it has never met. It cannot know your threshold, so its intervals are percentages of a number it invented. It cannot know whether your event is a short sharp effort or a long steady one, that you can only train Tuesdays and one weekend day, or that you spent the winter off the bike. It also cannot change after week one, which is when a plan earns its keep.
How your plan is built
Your history goes in first, and your thresholds are estimated from real efforts rather than typed in once and left to drift. Your course goes in next, with its length, its gradient and the wind the day is likely to bring. Your available days go in as a constraint the engine must respect rather than a suggestion.
Then the season is laid out backwards from race day. Early weeks tackle the abilities furthest from the event. Late weeks tackle the most event-specific work, which here means sustained efforts at the duration your course will last, ridden in position. The wider argument for planning a bike season from the course rather than the distance is in how guided bike plans are built.
Emphasis is not content. The gap that matters most sets what a block is for, while aerobic development, recovery and the abilities you already own stay protected.
What changes when your goal changes
The wizard asks what outcome you want, not only which race you entered. Five levels of ambition are offered, from getting round the course to a result you would call excellent, and every minimum scales with the one you pick.
Aiming at the top of that range rather than at completion means roughly twice the weekly training time and two more sessions a week, across a longer minimum build. Nothing about the event changed. The plan did, because it is solved rather than selected.
What a week actually looks like
At the session floor shown above, only one or two rides in a week are hard. One key session carries the block's focus, which becomes sustained work in position as the event approaches. The rest is aerobic riding at an intensity that lets the key session land, plus scheduled recovery.
The weekly hours shown are a destination, not week one. The ramp toward them is bounded by what you have recently been doing, so a rider coming off a quiet winter grows into those hours rather than being handed them.
When life interferes
Missed sessions are forgiven and never stacked onto the following week. Illness suspends the plan and rebuilds toward the level you had actually reached rather than the level the original plan projected, and the honest new forecast goes in front of you.
Small adjustments can apply on their own. Anything significant, such as changing the primary focus or restarting you after an interruption, waits for your approval. Nymiva gives training guidance and not medical care, so health concerns are escalated to you rather than diagnosed.
Questions people ask
Do I need a power meter?
No. The plan is built, progressed and adapted whether your rides carry watts or not. What degrades is the precision of the diagnosis, never the planning. Heart rate and perceived effort are first-class inputs, and anything that genuinely requires power is shown as absent with a reason instead of estimated into something that resembles data.
How far out should I start?
The minimum length above is the shortest plan built for this event at the finishing tier. A more ambitious goal raises that floor, and a season can run up to a year. Starting earlier is not training harder for longer, it lets the ramp stay inside safer bounds.
Can I train for this without a time trial bike?
Yes, and the plan is clear about the limit. Aerobic and threshold work transfers between bikes. Time in an aerodynamic position does not, so if you will race in the bars, the specific weeks need to be ridden there.
What if my event is a road race instead?
The demands change completely, because a road race is a hundred small efforts rather than one long one. The road race plan is built around the climbs on your course instead of a single sustained duration.
