Why a Hilly Half Is a Different Race
A flat half marathon rewards holding one pace for 13.1 miles. A hilly half asks for three different skills: climbing without blowing up, descending without wrecking your quads, and running the flat sections in between on tired legs. Your flat half PB won't tell you how you'll get on.
The good news is that hill fitness is very trainable, and you have time. The Keswick Half Marathon is on Sunday 19 September 2027, starting at 11am in Portinscale. That's just over 50 weeks away: enough for a newer runner to build up properly, and for an experienced runner to arrive stronger on the climbs than ever.
This guide is how we coach runners for hilly road halves at Townshend Performance. It covers the principles, the key sessions, and what a training week looks like whether you're a beginner, intermediate or advanced runner.
Know the Course
The Keswick Half is a road race, but a demanding one: 13.1 miles with 367m of climbing and a high point of 176m (race route). The climbing is front-loaded, so how you run the first eight miles decides how the last five feel.
- Portinscale into the Newlands loop. You start just past the suspension bridge in Portinscale and are climbing within the first couple of miles. Expect short, steep pitches on narrow lanes, with quick dips in between.
- Stair to the road under Cat Bells. The hardest sustained climbing comes as you leave Newlands via Stair. It brings you onto the road along the flank of Cat Bells, with big views down Borrowdale.
- The descent to Grange. A long, fast downhill takes you to Grange Bridge at 8.5 miles. Run it well and you gain time; run it badly and your quads pay for it later.
- The Borrowdale road back to Keswick. The last stretch along the east shore of Derwentwater is mostly flat, with long, gentle drags. Two roundabouts bring you into town and the finish at Keswick Rugby Club.
- Water stations sit at roughly 3, 6, 8 and 10.5 miles.
- Roads stay open to traffic. You keep right until Grange Bridge, then left.
- Runners who haven't reached Grange Bridge by 1pm, two hours after the start, are offered a lift back or can finish unaided at their own risk. That's roughly 14 minutes per mile, well within reach of a properly trained beginner.
- The course record is 1:10:37, set by Daniel Connolly in 2025.
The Five Principles
Train the three things this course asks for: aerobic endurance, climbing strength and descending durability.
- Build the engine first. Around 80% of your running should be at an easy, conversational effort. A big aerobic base is what lets you climb without tipping into the red, and it's built slowly.
- Run by effort, not pace. On a steep climb your pace can drop by minutes per mile at exactly the same effort. Use perceived effort or heart rate on hilly runs, and only judge pace on the flat.
- Rehearse the course. Keswick serves up short, steep climbs, a long descent, then a flat run-in on tired legs. Your key sessions should practise each of those, in that order where you can.
- Train the downhills, not just the climbs. Descending loads your quads eccentrically, as the muscle lengthens under load, and that causes most post-race soreness. Regular downhill running triggers a protective adaptation, the repeated bout effect, so the same descent does less damage next time.
- Build gradually, then recover. Add volume steadily, with an easier week every third or fourth week. Fitness is built in the recovery, not in the session itself.
The Key Hill Sessions
Six sessions cover everything Keswick will ask of you. You won't do all of them every week; your level and training phase decide the mix.
| Session | How to run it | What it builds | Who it's for |
|---|---|---|---|
| Hill sprints | 6–10 × 8–10 s flat out up a steep hill; walk down and take a full 2 min recovery | Leg power and economy, with very little fatigue | Everyone, from week one |
| Short hill reps | 6–10 × 60–90 s at 5K–10K effort; jog back down | Climbing strength and top-end aerobic fitness | All levels |
| Long hill reps | 4–6 × 3–5 min at threshold (comfortably hard) effort; jog back down | Holding effort on sustained climbs like the one out of Stair | Intermediate and advanced |
| Rolling tempo | 20–40 min at threshold effort on an undulating road, effort steady up and down | Even effort over changing gradients | Intermediate and advanced |
| Downhill strides | 4–6 × 30–60 s down a gentle 4–6% slope, smooth and quick; walk back up | Descending skill and quad durability | Everyone, built up gradually |
| Hilly-to-flat long run | Hilly first two-thirds at easy effort, then the last 2–4 miles on the flat at steady or race effort | Running strongly on tired legs, just like the Borrowdale road | Everyone, in the last 12 weeks |
Start every hill session with 10–15 minutes of easy running and finish with 10 minutes easy. On rep sessions, the recovery jog or walk back down is part of the session, so take all of it.
Climbing Technique
- Shorten your stride and lift your cadence: small, quick steps.
- Stay tall, lean slightly from the ankles, and drive your arms.
- On the steepest pitches, a strong power-walk can be almost as quick as a slow run and costs far less. If you're likely to finish over two hours, practise it in training.
Descending Technique
- Lean gently with the slope rather than sitting back.
- Land under your hips with quick, light steps. Overstriding and braking on your heels is what shreds your quads.
- Relax your shoulders and use your arms for balance.
Strength and Conditioning
Two 20–30 minute strength sessions a week will do more for your Keswick time than one more easy run. Strong legs climb more efficiently, and they're far harder to damage on the descents.
Session A: Legs (about 30 minutes)
Do this after your hill session, when your legs are already working hard.
| Exercise | Sets × reps | Why it matters for Keswick |
|---|---|---|
| Split squat (both feet on the floor) | 3 × 8–10 each leg | Single-leg strength for climbing |
| Step-up (start on a 10–25 cm step) | 3 × 8–10 each leg | Copies the push of a steep climb |
| Slow step-down (10–25 cm step, 3–4 s lowering) | 3 × 6–8 each leg | Eccentric quad strength for the descent to Grange |
| Single-leg Romanian deadlift | 3 × 8 each leg | Glutes, hamstrings and balance |
| Calf raise, straight and bent knee | 3 × 12–15 | Calves and Achilles for steep gradients |
| Tibialis raise (back against a wall, lift your toes) | 3 × 15–20 | Shin strength to absorb each foot strike on the descents |
| Pogo hops, then bounding | 2–3 × 10–20 contacts | Springiness and economy (advanced runners, from spring) |
Session B: Core, Hips and Posture (about 20–25 minutes)
Lighter on the legs, so do it after your second hard session of the week.
| Exercise | Sets × reps | Why it matters for Keswick |
|---|---|---|
| Single-leg balance (barefoot; eyes closed to progress) | 3 × 30 s each leg | Foot and ankle stability on cambered, uneven lanes |
| Dead bug (slow, lower back pressed to the floor) | 3 × 8–10 each side | Core control to stay tall and efficient on the climbs when you're tired |
| Russian twist (feet on the floor to start) | 3 × 10–12 each side | Trunk rotation control for a strong arm drive up steep pitches |
| Lying leg raise (knees bent to start) | 3 × 8–12 | Lower-abdominal and hip-flexor strength to keep your knee drive going on the climbs |
| Clamshell (add a mini band when easy) | 3 × 12–15 each side | Glute strength to keep your hips and knees stable on the descents |
| Bird dog (slow, hips level) | 3 × 8–10 each side | Links your back, glutes and shoulders so your stride stays stable |
| Superman hold (lying face down) | 3 × 20–30 s | Upper back and posterior chain to hold an upright posture in the last miles |
Start with bodyweight and add load once the last two reps feel easy. For step-ups and step-downs, begin on a 10–15 cm step, such as a thick book or yoga block, and progress to 20–25 cm before going any higher. Keeping strength work on hard days, after the run, means your easy days stay genuinely easy. Drop to one light session in the final fortnight before the race.
Training at Your Level
The principles don't change from beginner to advanced; the volume, intensity and number of hard sessions do. Find your starting point, then use the sample week as a guide for your peak block next summer.
- Beginner. You can run for about 30 minutes and this will be your first half. If you can't yet, start with run-walk three times a week. Most people reach 30 minutes of continuous running in 8–10 weeks, and you have 50. Your goal is to finish strong and enjoy it.
- Intermediate. You've run a flat half or a few 10Ks and run three or four times a week. Your goal is to run the hills with confidence and finish faster than you think a hilly course allows.
- Advanced. You race regularly, run five or six times a week, and want a time or a placing. Your goal is to race every section: the climbs, the descent and the run-in.
A Sample Peak-Phase Week (June to August 2027)
| Day | Beginner | Intermediate | Advanced |
|---|---|---|---|
| Mon | Rest | Rest | Easy 40–50 min |
| Tue | Easy 30–40 min + 4–6 hill sprints, then strength | Short hill reps: 8–10 × 90 s at 10K effort, then strength | Long hill reps: 5–6 × 4 min at threshold effort, then strength |
| Wed | Rest or easy cross-training | Easy 45 min | Easy 60–70 min |
| Thu | Short hill reps: 6–8 × 60 s, walk down, then strength | Rolling tempo: 3 × 10 min at threshold, 2 min jog, then strength | Rolling tempo: 2 × 20 min at half-marathon effort, then strength |
| Fri | Rest | Rest | Rest or 30 min recovery jog |
| Sat | Easy 30 min + 3 downhill strides | Easy 40 min + 4 downhill strides | Easy 45 min + 6 hill sprints + 4 downhill strides |
| Sun | Long run building to 2 hrs on a hilly route; walk the steepest pitches | Hilly-to-flat long run, 1:45–2:00 | Hilly-to-flat long run, 1:45–2:15, last 4 miles at race effort |
| Week total | About 4 hrs running, 4 runs | About 5–5.5 hrs running, 5 runs | About 7–8 hrs running, 6–7 runs |
Earlier in the year, the same week carries less volume and fewer hard sessions. A sample week is a starting point, not a plan. The right week for you depends on your history, your life and how you respond, and that's exactly what coaching adjusts as you go.
Stepping-Stone Races
Three races across the year turn a long build into manageable steps. Each one is a fitness check and a dress rehearsal, so you can practise pacing on climbs, fuelling and kit well before 19 September.
| When | Beginner | Intermediate | Advanced |
|---|---|---|---|
| Winter (Dec–Jan) | parkrun | parkrun or 5K | 10K |
| Spring (Mar–Apr) | 10K | 10K or flat half | Flat half |
| Early summer (Jun–Jul) | Hilly 10K | Hilly 10K or short fell or trail race | Hilly half or trail race |
Treat them as part of training rather than goal races: keep your normal week around them, then take a few easy days afterwards. Leave at least six weeks between your last stepping stone and Keswick.
Race Day
Start controlled, climb on effort, let the descent flow, and save something for the Borrowdale road.
Pacing
- Set a realistic target first. Put 21.1 km, 367m of ascent and your flat half-marathon pace into our free Hill Pace Calculator for a ballpark finish time.
- Nearly all the climbing comes before Grange. Keep the effort controlled through Newlands: nobody wins Keswick Half Marathon on the first hill, but plenty lose it there.
- Run the climbs on effort and let the pace go. If your run is barely faster than a walk on the steepest pitches, walk them strongly.
- Let the descent to Grange flow with quick, relaxed steps rather than braking all the way down.
- The Borrowdale road is where your race is made. Paced well, this is where you pass people.
Fuelling
- With an 11am start, eat a carb-based breakfast you've tested in training about three hours before, around 8am.
- If you'll be out for longer than about 90 minutes, aim for 30–60 g of carbohydrate an hour, starting 30–45 minutes in. Practise this on your long runs, not on race day.
- Water is at roughly 3, 6, 8 and 10.5 miles. Carry your own gels if you use them.
Your Head
- Break the race into four chunks: Newlands, the climb up to Cat Bells, the descent to Grange and the run-in. Only ever race the chunk you're in.
- Pick a short cue for the hard moments, like “smooth and strong”, and practise it in your hill sessions. Studies of endurance athletes show motivational self-talk lowers perceived effort and helps you hold on for longer.
- Picture the biggest climb in the week before the race, so it already feels familiar on the day.
Logistics and Kit
- Collect your number at Keswick Rugby Club on Saturday 18 September (3–5pm) or race morning (9–10:30am). The Portinscale start is about a 20-minute walk away, so head over by 10:30am.
- Your timing chip is in your race number. Wear it on the front, uncovered and unfolded.
- Race in road shoes you've done long runs in, with decent grip for damp lanes. September in the Lakes changes fast, so bring a layer for before and after.
Six Mistakes We See Every Year
- Easy runs too fast, hill sessions too hard. Grey-zone effort leaves you too tired for quality and too slow to build the base. Keep easy, easy.
- Only training the climbs. Runners who never practise descending reach Grange with battered quads and crawl the last five miles.
- Judging hilly runs by pace. A slow split on a steep climb isn't a bad run. Judge it on effort, or by grade-adjusted pace.
- Doing every long run on the flat. Your legs need to learn what 13 miles of up, down and flat feels like before race day.
- Skipping strength work. It's the first thing to go when life gets busy, and the main thing that keeps you injury-free through a 50-week build.
- Going off too hard in Newlands. Fresh legs, crowds in Portinscale and race-day adrenaline make the early climbs feel easy. Bank patience, not time.

Frequently Asked Questions
When is the Keswick Half Marathon 2027?
Sunday 19 September 2027, starting at 11am in Portinscale and finishing at Keswick Rugby Club. Numbers are collected at the rugby club on Saturday 18 September (3–5pm) or on race morning (9–10:30am).
How hilly is the Keswick Half Marathon?
It is a road race with 367m of climbing and a high point of 176m. The climbing is front-loaded: short, steep pitches through the Newlands valley, the hardest sustained climb out of Stair onto the road under Cat Bells, then a long descent to Grange Bridge at 8.5 miles and a mostly flat run-in along the Borrowdale road to Keswick.
Is there a cut-off time for the Keswick Half Marathon?
There is a time check rather than a hard cut-off. Runners who haven't reached Grange Bridge (8.5 miles) by 1pm, two hours after the start, are offered a lift back or can finish unaided at their own risk. That is roughly 14 minutes per mile, well within reach of a properly trained beginner.
How long does it take to train for a hilly half marathon?
If you can already run for about 30 minutes, a 50-week build to the Keswick Half gives you more than enough time. If you can't yet, start with run-walk three times a week: most people reach 30 minutes of continuous running in 8–10 weeks. A beginner's peak week is about four hours of running over four runs; an advanced runner's is seven to eight hours over six or seven runs.
Should I walk the hills in a hilly half marathon?
On the steepest pitches, if your run is barely faster than a walk, walk them strongly. A good power-walk can be almost as quick as a slow run and costs far less. If you are likely to finish in over two hours, practise it in training so it feels natural on race day.
How should I pace a hilly half marathon?
Run the climbs on effort and let the pace go, keep the first eight miles controlled, let the descent flow with quick, relaxed steps rather than braking, and save something for the flat run-in, which is where a well-paced race is made. For a ballpark finish time, put the distance, total ascent and your flat half-marathon pace into a grade-adjusted hill pace calculator.
