Marathon Coaching
16 Weeks to a New Personal Best
Built on your strengths and schedule.
Reviewed every week by your coach.
Personalized at Every Level
Every workout
Every session is chosen for a specific purpose and adapted to your strengths, weaknesses, and current fitness. I set your training zones from a recent race or time trial, and update them as your fitness changes across the block.
Every week
I build your week around your preferred running days and space the key sessions to match your recovery profile. Leave a note after any session and I rebuild the next week around your feedback and training data.
Every question
Message me on WhatsApp any time, and you get a reply within 12 hours, seven days a week. A niggle, a session that went wrong, a fueling question, you get an answer before the next run.
Athlete Results
The structure and guidance helped me execute a new marathon PR with a first place overall finish in 2:39:37 on a hilly course. Sandro’s scientific approach ensures that every run and workout has a purpose, arriving at the starting line fit, healthy, and fresh.
James Mount
United States
Sandro’s very well thought out coaching has assisted my running greatly, being able to fit my runs around the changing hours I work with my job. I am certain I would not have managed a 2:58 marathon PB at 45 years old without Sandro’s coaching.
Richard Leary
New Zealand
Sandro’s expertise and attention to detail has helped me improve more than I had thought possible. Through his online coaching, I broke my 20 year 5K PR by 21 seconds to 15:48 and I was able to break my half marathon PR by almost 4 minutes to 1:14:29.

16-Week Marathon Preparation
01 Foundation
Weeks 1 to 4 build the aerobic base everything else sits on. Steady mileage, hills, and strides to prepare your legs and tendons for the harder work ahead, so the next phase does not arrive too soon.
02 VO2 max
Weeks 5 to 8 raise your maximal aerobic capacity early in the block. A higher ceiling means you can hold threshold and marathon pace at a faster speed later, when the training gets more specific.
03 Threshold
Weeks 9 to 12 build the fatigue resistance the marathon demands. Sustained work at and around threshold, long runs that get progressively harder, and one VO2max session every 14 days so the ceiling you just built holds.
04 Peak
Weeks 13 to 16 turn fitness into race readiness. Marathon pace volume, fueling rehearsal in the long runs, and a taper that leaves you sharp rather than flat on the start line.

All coaching and communication is handled directly by me, Sandro Sket. I don’t outsource coaching or delegate athlete management to assistants. My approach is based on the belief that training decisions and performance oversight require direct involvement to maintain quality and consistency.
To ensure that level of attention, remote coaching is intentionally limited to a small number of athletes.
If injury stops your training before week 8, you carry the block to any race within 12 months at no extra cost. Tell me in WhatsApp when it happens and we sort out the timing together.
Yes, I coach runners at different performance levels, but the common thread is intent. This block is built for runners who train consistently, want feedback, and have a marathon on the calendar they care about.
Coaching starts with understanding your current fitness, training history, and your goal race. I build your training around that context and adjust it continuously based on how you respond to the training stimuli.
Your training is reviewed regularly using your training log data and your feedback in the comment section. Based on that, I update sessions week to week to manage load, progression, and recovery so training remains productive and sustainable as fitness develops. All workouts include clear instructions and can be uploaded to your watch for execution.
Over the sixteen weeks your training moves through four phases, and each one is built on what you actually completed in the last.
Training is delivered through FinalSurge by default. TrainingPeaks is available for athletes who prefer to stay on that platform. I initiate coach-led email reviews each Sunday. You can also reach me on WhatsApp whenever questions come up during the week.
That depends on where you’re starting. A runner with three years of training and no structure has more to gain than someone already doing the right work at the right volume. What I can tell you is where the gains come from: raising your ceiling early, then spending eight weeks building what you can hold beneath it.
I don’t promise a time. Any coach who does is guessing at your genetics, your consistency, and race day weather. What I promise is that every session has a reason, and that the plan changes when your training says it should.
Sign up for the 16 week block. I’ll email you to ask about your running background, your goal race, and where your training stands now.
From there you set up a free FinalSurge account and add me as your coach. Your plan is built around your paces and your training days, and week one starts as soon as it’s in.
