How to shave time off your marathon PB while running less

Sooke, B.C’s Kate Guy says that at 45, she is only getting faster in the marathon, and is close to breaking the three-hour mark, despite running less volume than she used to in her training.

The full-time consultant has been running for more than 20 years, and last week, ran her fastest Boston Marathon yet (3:10). It wasn’t until she started prioritizing quality work in every single run that she started seeing her marathon times drop significantly. She ran a three-hour marathon last year and now has her sights set on sub-three this summer.

Guy says that her run training has changed a lot in the two decades she’s been running, and the biggest difference is that she has cut out almost all “slow” running. She runs three or four times per week and ensures that these runs are packed with quality.

“In my experience, focusing on running at marathon pace is more helpful than long, slow, running” Guy says, when talking about where she prioritizes time on her feet. “If you only train your body to run slow, then you cannot expect to perform at a faster pace miraculously on race day.” 

As it turns out, Guy finds value in keeping some cycling in her weekly training. She credits this cross-training approach to her recent speed boost and history of staying injury-free (Guy has not had any major running injuries in her 20 years in the sport).

“On the weekend, I do a long bike (two to three hours) on Saturday, followed by my long run on a Sunday,” she explains.  “This is great, because my legs aren’t feeling fresh on Sunday, and it promotes running on tired legs, like you would at the middle to end of a marathon.”

Without easy runs in her week, Guy prioritizes three types of run sessions in her training: speed work, hill repeats, and long runs with tempo running sandwiched in. For the latter, there are three main long run workouts she follows:

Over-unders

5 km easy warmup 

3x (1 km at 15 seconds faster than goal marathon pace, 1 km at 15 seconds slower than goal marathon pace) 

easy cooldown 

Long run at race pace

20 to 30 minutes easy warmup

2 hours at goal marathon pace

15 minutes easy cooldown

Progression long run:

Running for 2.5 hours: start easy and every 30 minutes, increase pace by 15 to 20 seconds per kilometer 

High-volume running will always be the training method of choice for many top runners and coaches, but Guy proves that a different approach can produce the same results for amateur runners looking to maximize their available training time. For injury-prone runners, dialing back on volume but increasing quality and keeping in lots of cross-training may be the key to consistent improvement across long distances.

“This training style is definitely underrated, but my results demonstrate that you can get faster as you age, with less stress on your body,” Guy says.
