Gran fondo training
Free Gran Fondo Training Plan
A gran fondo is a long mass-participation ride, usually 100 to 200 km and often with serious climbing. It rewards a big aerobic engine, the ability to hold a strong effort on long climbs, and steady fuelling over four to eight hours.
- Typical event
- 100 to 200 km, often 1,500 to 4,000 m of climbing
- Typical build
- 8 to 16 weeks
- Weekly time
- 6 to 12 hours
- Taper
- 7 to 10 days
How a gran fondo plan is structured
A gran fondo build typically runs 8 to 16 weeks. The first block extends your long ride and adds tempo and sweet spot work. The second block adds threshold and climbing-specific sessions. The last block rehearses the event with long rides at target effort and then tapers. Most of your riding stays at easy endurance effort, with two quality sessions a week and a lighter week every three or four.
Test your FTP and train by zones
Functional threshold power, roughly the power you could hold for about an hour, anchors every session. A common estimate is 95 percent of your best 20-minute average after a proper warm-up, or a ramp test. Endurance rides sit around 56 to 75 percent of FTP, sweet spot at 88 to 94, threshold at 95 to 105. Without a power meter, heart rate and perceived effort work too: endurance is fully conversational, sweet spot is a few words at a time.
Sweet spot and threshold sessions
Sweet spot gives a lot of aerobic stimulus for its cost: 3 × 15 minutes or 2 × 20 minutes at 88 to 94 percent of FTP with 5 minutes easy between. Threshold work, such as 4 × 8 minutes at 95 to 105 percent, raises the ceiling. On a hilly course, do some of these on climbs, seated and at a lower cadence, to rehearse how the event will feel.
The long ride and fuelling
The long ride builds toward 70 to 80 percent of the event's expected duration, at endurance effort with a few blocks at target pace on climbs. It is also where you train fuelling: most riders need 60 to 90 grams of carbohydrate per hour on rides this long, starting in the first 30 minutes, plus fluid and sodium matched to the heat. Running out of energy at kilometre 120 is a fuelling problem, not a fitness one.
Pacing the day and the taper
Most riders should ride a long fondo at around 65 to 75 percent of FTP overall, and keep climbs below threshold early in the day. Join groups on the flats to save energy but do not chase surges. In the final 7 to 10 days, cut volume by about 40 to 50 percent and keep a couple of short efforts at sweet spot or threshold to stay sharp.
A sample week
A build-phase week of about 8 to 9 hours. With less time, keep the sweet spot session, the threshold session and the long ride.
- Mon
- Rest
- Tue
- Sweet spot, 75 min: 3 × 15 min at 88 to 94 percent FTP, 5 min easy between
- Wed
- Endurance ride, 60 min at 56 to 75 percent FTP, high cadence
- Thu
- Threshold, 75 min: 4 × 8 min at 95 to 105 percent FTP, on a climb if possible
- Fri
- Rest or 45 min recovery spin
- Sat
- Long ride, 4 h at endurance effort, climbs at target pace, fuelling 60 to 90 g/h
- Sun
- Endurance ride, 90 min easy, or a short run or strength session
The mistake most fondo riders make
Riding the first climb at threshold because everyone around you is. The adrenaline of a mass start makes the first hour feel easy, and the last two hours expose it. Ride your own effort from the start, eat early, and you will pass people on the final climb instead of being passed.
Common questions
How long does it take to train for a gran fondo?
Eight to sixteen weeks if you already ride regularly. Newer riders should spend a few extra weeks building up to comfortable two to three hour rides first.
Do I need a power meter?
No. A power meter makes pacing more precise, but heart rate and perceived effort work well. The plan gives targets in whichever you use.
How should I fuel a gran fondo?
Most riders need 60 to 90 grams of carbohydrate per hour, starting early and practised in training, plus fluid and sodium matched to the conditions.
Is the cycling plan free?
Yes. AthleteSpace is free with no credit card, and it reads your rides from Strava, Garmin, Wahoo and others to adapt the plan.
