Cycling fitness and health for delivery riders

Summary

Delivery riding on a bike or e-bike can be great for your fitness. It can also wreck your knees, back, hands and diet in 2025-26 if you are not careful.

The goal is not "cycle more". You already are. It is a better bike setup, real food and drink, basic stretching, and knowing when to rest, so you can still ride in five years.

NHS and physio guidance is clear: regular cycling is healthy. But too much, too dehydrated, with bad posture turns gig riding from fitness into a steady stream of overuse injuries.

Key facts (UK 2025-26)

• NHS England says regular physical activity like cycling cuts the risk of major diseases (heart disease, stroke, type 2 diabetes, some cancers) and that the benefits far outweigh the risks when it is done sensibly.
• A 2023 review of cycling health data found that people who cycle have a lower risk of death from any cause and lower rates of cardiovascular disease and type 2 diabetes compared with non-cyclists.
• The same review warns that cycling can cause overuse injuries, especially to the knees, and may not be enough on its own to protect bone health; riders should add some weight-bearing work such as walking or strength training.
• Physio data suggest that up to 45% of overuse injuries in cyclists affect the knee, often due to poor bike fit or doing too much too fast.
• NHS hydration guidance says most adults in the UK need around 1.5 to 2.5 litres of fluid a day in normal weather (about 6 to 8 glasses) and more when working hard or in the heat.
• NHS hot-weather advice says to avoid heavy exercise between 11am and 3pm, drink plenty of cold fluids, avoid excess caffeine and alcohol, and stay in the shade when possible. All directly relevant to summer shifts.

Legislation, case law, regulation

There is no single "Cycling Health Act", but several rules and bits of guidance matter for fitness and health:

• Health and safety law (Health and Safety at Work etc. Act 1974) largely targets employers, so as a self-employed rider you do not get a safety office forcing breaks. The burden of managing workload and rest falls on you.
• The Highway Code rules for cyclists (which underpin road law) indirectly affect health by setting expectations on lights, clothing and visibility, which all link to crash risk and therefore injury risk.
• NHS public-health guidance on physical activity and hot weather is not "law", but is the official reference for what is considered safe and healthy activity levels and hydration in the UK in 2025-26.

How it actually works

1. What delivery riding does to your body

Gig riding is not like a short commuter ride. You are dealing with:

• Hills and stop-start traffic: repeated hard efforts, especially on heavy e-bikes or with loaded bags.
• Weight: big backpacks or side bags loaded with food or parcels add constant strain to your shoulders, back and knees.
• Repetitive motion: thousands of pedal strokes in the same range of motion, day after day; that is how overuse injuries happen.
• Weather: heat, cold, wind and rain all make your body work harder, dehydrating you faster or chilling your hands, feet and chest.

Done right, this is a free gym membership. Done wrong, it is a slow injury.

2. Nutrition and hydration on shift

What to eat

You need steady energy, not just sugar hits. Practical options:

• Before or early in a shift: oats, bananas, yoghurt, wholegrain sandwiches, nuts. Food with carbs plus some protein and fat.
• During: small snacks every couple of hours (bananas, nuts, oat bars, hummus wraps) rather than huge meals that leave you sluggish.

Constant fast food from pickups (chips, burgers, giant desserts) is convenient. It also spikes your energy then crashes it, and over months it hits your weight, blood sugar and heart.

Hydration

• Aim for at least 1.5 to 2.5 litres of fluid across the day in normal UK weather, more when you are sweating or in heat.
• Water, diluted squash and non-sugary drinks are best; NHS heat guidance suggests cold drinks and avoiding too much alcohol and caffeine in hot weather.
• In summer or on long shifts, carry a bottle you can refill; if your urine is very dark or you stop needing to pee, you are already behind on fluids.

3. Injury prevention: knees, back, hands, saddle

Knee pain

Very common in riders. Physio data say around 45% of cycling overuse injuries hit the knee. Common causes:

• saddle too low (puts pressure on the front of the knee),
• pushing big gears at low cadence,
• sudden jumps in weekly hours.

Back and shoulders

• Heavy backpacks sitting too low, or slumped posture, strain your spine all shift.
• Use racks or frame-mounted bags where possible so the bike carries the weight.
• If you must use a backpack, keep it high and close to your body, with both straps tight.

Hands and wrists

• Constant pressure on the bars plus rough roads can cause numbness or pain.
• Slightly bend your elbows, do not lock them straight.
• Change hand positions when you can.
• Padded gloves help.

Saddle soreness

• Common with long hours.
• Check saddle height and tilt (flat or very slightly nose-down).
• Good padded shorts and breathable underwear help.
• If pain is severe or persistent, get a proper bike fit or see a physio or GP.

NHS knee-pain leaflets stress: work within pain limits, do simple strengthening exercises and seek advice if pain persists or worsens.

4. Bike setup for delivery work

You do not need a pro fitting, but a few key rules will save your joints.

• Saddle height: a rough guide is heel on the pedal at the bottom stroke with your leg almost straight; when you ride normally with the ball of your foot, your knee should stay slightly bent.
• Reach and handlebar height: you should be able to reach the bars without locking elbows or hunching shoulders; too long a reach = back and neck pain.
• Bag mounting: if your platform or setup allows, rear racks and panniers are far better than massive backpacks for long shifts; splitting weight between bike and body takes strain off your spine and knees.

Getting these three roughly right is the simplest way to stop normal gig mileage turning into long-term pain.

5. Simple stretching and off-bike work

You do not need yoga retreats. You need 5 minutes before and after.

Typical pre- and post-shift moves based on physio advice:

• gentle calf and hamstring stretches (back of lower leg and thigh),
• hip flexor stretches (front of the hips) to balance all that sitting and pedalling,
• light quadriceps stretches (front of thigh),
• a few shoulder rolls and chest stretches to open up after backpack use,
• a small set of glute and core exercises on off days (bridges, side planks) to support knees and lower back.

Simple rule: if something is tight or sore, work on it daily. Ignore it and it becomes a proper injury.

6. Winter riding health

Cold shifts bring their own risks.

• Hypothermia: long periods wet and cold can drop your core temperature; shivering, confusion and extreme tiredness are danger signs.
• Cold hands and feet: they are not just uncomfortable; they slow reaction time and control. Thermal gloves and socks, plus windproof layers, really help.
• Breathing cold air: some riders get chest tightness or coughs; a buff or light mask can warm the air a bit, and if you have asthma or similar, your inhaler plan matters.

NHS hot-weather advice gets more attention, but the same logic applies in the cold: dress for the conditions, do not ride through extreme weather, and do not push so hard you lose feeling in your fingers or toes.

7. The "exercise paradox" of delivery riding

It is easy to think "I ride all day, so I must be super fit". The reality:

• You are doing lots of low-to-medium intensity work, but often with poor food and sleep.
• You may lack strength work and bone-loading exercise, which matters for long-term bone and joint health.
• Overuse without recovery leads to injuries. The problem is not cycling too much. It is doing the same movement all day, every day, with no strength work, stretching or rest to balance it.

Riders who still feel good after years usually:

• eat like athletes, not bins,
• add a bit of cross-training (walking, light strength work, stretching),
• treat pain as an early warning, not a test of toughness.

Worked example

Amal is 19 and does Deliveroo and Uber Eats on an e-bike in Manchester, earning around £180 a week in 2025-26 by working 4 to 5 evenings.

Year 1 pattern:

• Eats whatever is easiest near pickups, usually burgers or fried chicken.
• Drinks energy drinks all shift, little water.
• Rides with a huge backpack hanging low.
• Does no stretching, works through knee niggles.

By winter, he has:

• aching knees on hills,
• lower-back pain after long shifts,
• days of feeling wiped out and "wired but tired".

He decides to treat it like a sport, not just a hustle:

• He adjusts saddle height and moves the seat slightly back; knees feel less jammed on each stroke.
• He buys a rack and panniers, so the bike carries most of the weight.
• He switches to bringing a simple packed meal and snacks (pasta, wraps, bananas, nuts) and a 1-litre water bottle he refills mid-shift.
• He adds a 5-minute stretch before and after and a short glute/core session twice a week.
• In hot weather he avoids the 11am to 3pm window where possible, tops up fluids, and cuts back on energy drinks.

After a couple of months, Amal is:

• less sore,
• less exhausted between shifts,
• making similar money without feeling wrecked.

He has not trained like a pro. He has just stopped letting the job batter his body for nothing.

What Reddit, TikTok and forums get wrong

1. "You're cycling, so you can eat whatever you like." Wrong. NHS and public-health data say exercise helps, but poor diet still raises risks for heart disease, diabetes and weight gain. Daily fried food and sugar bomb drinks will catch up with you, even if you are riding all evening.

2. "If your knees hurt, you just need to toughen up." Physio data show about 45% of cycling overuse injuries are knee-related; ignoring pain is how minor issues become long layoffs. Bike fit, gradual load and basic strengthening matter more than bravado.

3. "Gig riding makes you super-fit by itself; you don't need other exercise." Research suggests cycling is great for heart health but less good for bone strength on its own; some weight-bearing activity is still needed. Long-term health is about a mix: cardio, strength, mobility and recovery, not just more and more miles.

4. "Hydration's only an issue on crazy hot days." NHS guidance says dehydration and heat illness can hit in any heatwave or any hard physical day. "A couple of cans" is not hydration. Tired, dehydrated riders make worse decisions and crash more often.

Action steps for the reader

1. Check your saddle height and bar reach today using a basic online guide; if your knees are very bent at the bottom of the stroke, raise the saddle a little.
2. Move as much weight as possible from your back to the bike. Racks and panniers if you can; if you must use a backpack, tighten straps and keep it high.
3. For your next week of shifts, swap at least half of your "pickup fast food" for simple packed meals and snacks, and carry a refillable water bottle.
4. Build a 5-minute pre- and post-shift routine (legs, hips, back, shoulders); if pain continues, read NHS knee-pain and physio leaflets and speak to your GP or a physio.
5. On very hot days, avoid riding hard between 11am and 3pm if you can, follow NHS heat advice, and increase fluids.
6. Add at least one non-cycling activity per week (a walk, light strength session, or other weight-bearing exercise) to support bones and joints.
