Make The Next 20 Weeks Count

Stop guessing. Start building.

If you are already running but do not feel like you are progressing, constantly jumping between plans or simply do not know whether your training is moving you forward, Base to Best gives those months a purpose.

It is also ideal if you are targeting a spring marathon. We will use your March half to build your fitness, speed, strength and durability before moving into the final part of marathon preparation.

One Clear Journey

BASE

1. Establish The Base

We start by getting your training structure right, building consistency and establishing the right volume for you.

BUILD

2. Build

Progressively build your aerobic fitness, strength and training capacity without rushing into race-specific work too early.

PROGRESS

3. Progress

Training becomes more specific to your goal as we progress your threshold, long runs and key sessions.

BENCHMARK

4. Winter 10K

The team comes together for a benchmark race so we can see how far you have progressed.

BEST

5. Best Half Marathon

BEST – Run your best half marathon at Cambridge, Bath or your chosen race, backed by 20 weeks of structured training.

SPRING MARATHON?

6. Keep Building

If your half is part of a bigger goal, we carry the fitness you have built into the final stages of marathon prep.

This Isn't A Downloaded Training Plan

Your programme is built around you.

Your programme is built around your current fitness, goal, training history, available days and life outside running. Liam reviews your training throughout the 20 weeks and adapts it as you progress.

“My training had much more purpose and I could see the progress building throughout the programme. It all came together on race day when I ran my fastest ever 10K.”

Chris Whitehead

“The biggest difference was having a clear plan and a target to work towards each week. I finished with nearly a four-minute PB and my first sub-45.”

Jack Ephgrave

“Do it. Liam tailors the programme to your commitments and schedule, gives regular feedback, and the camaraderie between the other Run Stark athletes is a great support.”

April Wilson

Exclusive programme draw

Win a Pair of Supershoes

Every Base to Best athlete will automatically be entered into our exclusive programme draw to win a brand-new pair of supershoes before race day. This is a benefit for everyone taking part in Base to Best. It is separate from the Cambridge giveaway, although the giveaway winner will also be entered into the supershoe draw because they become a Base to Best athlete.

Questions?

Do I need a Cambridge place?

No. Base to Best is built around your goal, not one specific race. You can target Cambridge, Bath or another half marathon around the same period. If you are racing Cambridge, you will be able to join the Run Stark team on race day.

Is this suitable for a spring marathon runner?

Yes. A March half marathon is a great stepping stone towards a spring marathon. We will use Base to Best to develop your aerobic fitness, threshold, strength and durability before progressing into the final marathon-specific phase of your training.

Is it suitable for beginners?

Yes. You do not need to be a certain pace or running a particular weekly mileage. Your programme is personalised around your current fitness, experience and available training time. You just need to be ready to train consistently.

Does everyone get the same programme?

No. This is not a generic 20-week plan. Your training is built around your fitness, goals, training history, available days and life outside running. Your training is then reviewed and adjusted throughout the programme as you progress.

Do I have to attend the group events?

No. All group runs, coached sessions and events are optional. They are there to add to the experience and give you the opportunity to train with the Run Stark community, but your programme will still work if you cannot attend.

Is my race entry included?

No. Race entries are separate from the coaching programme. If you already have a Cambridge, Bath or another half marathon place, we can build your programme around it.
