The climb from Tovena
We do not have a reliable kilometre profile for the San Boldo, so we stick to the key figures. 451 metres of climbing over 6 kilometres means the road gains about 75 metres per kilometre on average. For a category 2 climb that is a solid value.
The 12 % peak sits four and a half percentage points above the average. Where exactly the steepest pieces are cannot be read cleanly from our data. What is clear is that the climb is short enough to ride at one steady effort from bottom to top. Anyone who starts too hard will still feel it before the pass.
How it compares to our 100 climbs
In our list the San Boldo is a special case: only two climbs finish lower than 706 m, only three have less climbing and only two are shorter. In the Eastern Alps it is the smallest of the 28 climbs on all three counts. The average tells a different story: at 7.5 % only 34 climbs in the list are steeper. The Muro di Sormano is similarly compact but even steeper, with 7.1 km and 623 m of climbing at 8.8 %.
Practical tips
With a finishing height of 706 m the San Boldo is no high mountain pass, so you do not need to dress as you would for the high Alps. A normal compact chainset is enough for the 12 % peak. Because the climb is short, it combines well with other climbs into a longer ride. On the north side you roll down to Trichiana in the Val Belluna.
