100 Miles: Training programme for an experienced cyclist

Don’t be fooled, 100 miles is a long way, circa 6hr without a stop (16.5mph average), completing your first 100-mile cycling ride is a challenge. It was more than just a test of fitness and endurance — it was a journey of preparation, determination, and resilience. 

Every training ride, early start, tough climb, and moment of doubt led to this milestone. Reaching the finish line after 100 miles is an unforgettable achievement and a reminder of what can be accomplished with commitment, patience, and a willingness to keep pushing forward.

With a long ride, I always break this down into 5 goals, first goal, 20 miles, second 40 miles etc, all the way to 100, with this, you are only looking at the next 20 in your head, before you know it, you’re at 60 miles or over halfway – only 40 to go, happy days. 

Fuelling is really important and don’t think you will be fine, fuelling for a long ride is easy to say but hard to do, something I set up years ago is, setting a reminder on a Cycling Computer/Phone to eat and drink every 20mins, this way you won’t forget, the most important thing to remember is “Little and Often”, a sip and a bite to eat is all you need, but start from the get go and then every 20mins and keep it up. 

Nutrition 

For rides longer than 2 hours: 

  • 60–90 g carbohydrate per hour  
  • Drink 500–750 ml fluid per hour (more if it’s hot)  
  • Aim for 500–800 mg sodium per hour  
  • Eat every 20–30 minutes rather than waiting until you’re hungry.  

Before long rides: 

  • Eat a carbohydrate-rich breakfast.

After rides: 

  • Aim for 20–30 g of protein plus carbohydrates within an hour to support recovery. 
  • Practice this on every long ride. 

Pacing for the 100 miles 

  • Ride the first 50 miles easier than you think you should.  
  • Stay mostly in Zone 2 on the flats.  
  • Avoid chasing other riders early.  
  • Eat from the first 20 mins, not when you feel hungry.  
  • If you feel strong after 75–80 miles, gradually increase your effort.  

 

The plan below should leave you well prepared to complete the ride strongly while minimising fatigue going into September 6 September.
