"Since I'm visiting Shiga, I want to cycle all the way around Lake Biwa in a single day!"
Many travelers and beginners arrive with this ambitious goal. Cycling along the lake—feeling the fresh breeze, discovering historic lakeside towns, and sampling local dishes—is an unforgettable adventure that everyone should experience at least once.
However, jumping straight into a single-day Northern Lake loop (approx. 150km) or a full Biwaichi (approx. 200km) without prior sports bike experience is a high-risk endeavor.

Note for Experienced Cyclists:
This guide is tailored specifically for beginners and newcomers to sports cycling. If you are already an intermediate or advanced road cyclist, these pacing guidelines do not apply to you—please trust your own stamina and personal distance benchmarks!

Here is an honest guide from a local cyclist on the physical "distance barriers" you will encounter, along with practical tips to build your stamina safely.

The 50km Barrier: Build Your Foundation with the South Lake

Unlike typical city bikes, lightweight sports bikes glide effortlessly. For the first 20km to 30km, you might feel like you could ride forever.
However, once you hit the 50km mark (around 3 to 4 hours of riding), your body begins to feel the unfamiliar strain of maintaining an aerodynamic posture. Beginners often rely solely on their front thigh muscles rather than utilizing their core and hips, which can trigger knee and lower back pain.
Start by riding the Southern Lake Loop (approx. 50km), crossing bridges like the Omi Ohashi or Biwako Ohashi. Your benchmark should be finishing the loop with a smile and zero lingering fatigue the following day. This forms the essential foundation for all endurance cycling.

The 100km Barrier: Managing Rest and Fuel

Once 50km feels comfortable, extending your route toward Hikone or Nagahama for a 100km round trip is the next milestone. At this distance, willpower alone is not enough.
During a 6-to-8-hour ride, running out of fuel (known as "bonking") is a real hazard.

  • Rest before fatigue sets in: Dismount your bike every hour to stretch your legs and lower back.
  • Fuel before hunger strikes: If you wait until you feel hungry or thirsty, dehydration and energy loss have already begun. Carry small portions of rice balls, sweets, or energy bars, and eat periodically throughout the day.

Why a 1-Day Biwaichi is Risky for Novice Riders

Only after completing multiple 100km rides with good energy management should you consider attempting a single-day loop. Here is why tackling 150km to 200km in one day is not recommended for beginners:

  1. Accident Risk from Exhaustion: After 100km, mental focus drops sharply. Riders are far more likely to misjudge road surface transitions, lose balance, or fail to notice approaching vehicles.
  2. Joint and Muscular Strain: Pedaling hundreds of kilometers with improper posture puts intense stress on knee tendons and lower joints, risking injuries that take weeks to heal.
  3. Rental Return Deadlines: If you use a rental bike, you must adhere to shop return hours. For instance, when renting a quality road or hybrid bike from lakeside hubs like Giant Store Biwako Moriyama (located inside the Lake Biwa Marriott Hotel), bikes must be returned by early evening. Racing against the clock creates unnecessary panic, which compromises safety and ruins the sightseeing experience.

The Recommended Progression for a Safe, Memorable Biwaichi

To truly appreciate Lake Biwa's landscapes and cultural heritage, take a gradual, well-paced approach:

  1. Step 1: Complete the Southern Lake Loop (approx. 50km) to get accustomed to riding a sports bike.
  2. Step 2: Plan a 2-Day, 1-Night trip around the Northern Lake (averaging 50km to 80km per day), allowing time for leisurely meals, photos, and sightseeing.
  3. Step 3: Attempt a single-day Northern Lake or Full Biwaichi only after gaining confidence with multiple 100km rides.

If traveling with your own bike on trains is inconvenient, utilizing local rental services right on the lakeshore is an easy and accessible alternative. Having a professionally tuned bike adjusted to your height makes a remarkable difference in comfort and endurance.
Lake Biwa isn't going anywhere—take your time, ride smart, and enjoy the journey!
