Sierra Loop – The Ultimate Training Ride East of Manila
Today's ride was one of the classic routes that nearly every serious cyclist in Metro Manila knows by name: Sierra Loop.
For many riders, Sierra Loop is the benchmark route. It's where people test fitness, prepare for races, build climbing strength, and spend hours in the saddle away from city traffic.
The beauty of Sierra Loop is its simplicity.
You leave the busy streets behind, head toward the foothills of the Sierra Madre mountain range, tackle several sustained climbs, enjoy incredible views over Rizal Province, and then finish the day with a fast descent and long rolling roads back toward civilization.
It's challenging enough to feel like an achievement, but accessible enough to become a regular training route.
And after riding it again today, it's easy to understand why it remains one of the most popular cycling routes in the Philippines.
Riding Through the Sierra Madre
The route takes riders through the eastern mountains of Rizal, skirting the edge of the Upper Marikina River Basin Protected Landscape.
This protected area is one of the last remaining large forest ecosystems close to Metro Manila and serves as an important watershed supplying water to millions of residents.
The roads here wind through rolling hills, forested ridges, small communities, and some of the most scenic mountain roads within riding distance of the capital.
Historically, these mountains have always acted as a natural barrier separating the coastal plains from the interior of Luzon.
Today, they provide something equally valuable for cyclists:
Elevation.
Lots of it.
Climb #1 – Cabading Climb
📏 2.49 km
⬆️ 89 m elevation gain
📈 3.6% average grade
🏔 Category 4
Cabading is the gentle introduction to the day.
Nothing too intimidating.
Just enough climbing to wake up the legs and remind you that the flat roads are over.
The gradients remain friendly throughout, making it the perfect warm-up before the bigger efforts begin.
Many riders make the mistake of pushing too hard here.
The smart move?
Save your legs.
The real work comes later.
Climb #2 – Full Radar Climb
📏 6.18 km
⬆️ 369 m elevation gain
📈 5.1% average grade
🏔 Category 3
This is where Sierra Loop starts getting serious.
The climb steadily gains elevation as the road winds deeper into the mountains.
Unlike short punchy climbs, Full Radar rewards patience.
The gradients aren't extreme, but they're consistent enough to wear riders down if pacing is wrong.
The road snakes through the hills, offering occasional glimpses of the valleys below.
It's a climb that teaches discipline.
Ride within yourself, find a rhythm, and keep turning the pedals.
By the summit, you'll know you've earned it.
Climb #3 – Sta. Ines Road Climb
📏 3.3 km
⬆️ 175 m elevation gain
📈 5.2% average grade
🏔 Category 3
The final major climb of the day.
And arguably the most deceptive.
The numbers don't look intimidating at first glance.
But by the time you reach Sta. Ines, the previous climbs have already taken their toll.
This climb feels steeper than the statistics suggest.
The road twists through the mountains, forcing riders to dig a little deeper for the final effort.
Fortunately, the reward comes quickly.
Because once this climb is done, the hardest work of the day is behind you.
Why Sierra Loop Is Such a Great Training Route
One of the best features of Sierra Loop is its structure.
Almost all of the meaningful climbing happens in the first half of the ride.
That means you can focus on your efforts early, manage your pacing, and then enjoy the second half without worrying about another major mountain waiting around the corner.
After the final climb, the route transforms.
The road opens up.
The views become spectacular.
And the long descent begins.
Fast corners.
Flowing roads.
Mountain scenery.
Cooler air.
Everything a cyclist wants after a morning of climbing.
The final kilometers are much flatter and allow riders to spin the legs, recover, and simply enjoy being on the bike.
More Than Just a Training Route
Sierra Loop has become something of a rite of passage among cyclists in Metro Manila.
Ask local riders about their first big ride, first century ride, or first serious climbing experience, and Sierra Loop often enters the conversation.
It's challenging but not overwhelming.
Scenic but still practical.
A route that can be ridden for fitness, adventure, or simply for the joy of spending a day on two wheels.
That's why thousands of cyclists return here again and again.
And after today's ride, it's easy to understand why.
Great climbs.
Great roads.
Great views.
Exactly what a training ride should be.
