Thayarunde Radmarathon Training Plan & Preparation

Course & Elevation

The Thayarunde road marathon covers a 100-kilometre loop through the Thaya valley around Waidhofen an der Thaya in Austria's northern Waldviertel region. Just over 1,000 metres of climbing make it a classic rolling course: roughly a third of the distance points uphill, a third downhill, and the rest is flat, with barely any sustained steep ground. The opening 27 kilometres stay calm before a sequence of short one-to-two-kilometre rises begins, including a longer two-kilometre drag at kilometre 57.

The decisive stretch arrives late. At kilometre 74 the hardest climb of the day kicks in, one and a half kilometres averaging 5.6 percent with ramps touching 16 percent, and barely two kilometres later another kilometre at around 7 percent follows with similarly sharp pitches. Riders with reserves left can press on over the final rollers at kilometres 81 and 89 on the run back to town.

The third edition doubles as the Austrian national championship for marathon road racing and is part of the Austria Top Tour, the country's largest marathon series, so the front of the field races accordingly. Start and finish are both in Waidhofen an der Thaya.

Pacing Strategy

The loop is classically rolling — roughly a third flat, a third uphill, a third down, about 10 metres of climbing per kilometre, but spread across many short rises rather than long ascents. What decides the race isn't strength on a single climb but staying in the bunch: in a championship the move happens in the draft and on the sharp ramps from kilometre 57 on. That's where the steepest kickers cluster — near kilometres 74 and 77 short pitches rear up over 16 percent, back to back.

Keep a deliberate reserve through the first half; the constant rises tempt you to crest every bump in the red and empty the tank before the hard ramps arrive. Ride the rollers evenly, stay glued to the groups, and save your matches for the steep block in the final third that settles the placings.

12-Week Preparation

For a typical age-group rider the course means two and a half to four hours of racing, most of it aerobic. The profile does not reward steady diesel power alone, though: the string of short climbs and the championship character of the race produce repeated accelerations just above threshold, followed by recovery in the descents and flat sections.

The race is usually decided at the double climb at kilometres 74 and 77. Both rises are only one to one and a half kilometres long, but they arrive after several hours of riding and contain ramps of up to 16 percent, exactly the kind of terrain where groups split. Lose contact there and you face the final rolling kilometres chasing organised groups on your own.

Preparation should emphasise three things. First, an aerobic base built on three-to-four-hour rides over rolling terrain. Second, repeated climbing efforts of two to five minutes at and slightly above threshold, so you can follow surges on the short climbs even late in the race. Third, group riding skills: drafting, fighting for position before each rise and descending confidently are worth many minutes on a course like this. Practising eating and drinking at race pace belongs on that list too, because a fast 100-kilometre race leaves few quiet moments to fuel.
