Thames Path kit list

I've just done my kit list for next week's Centurion Thames Path. I am hoping I can finish the 100 miles in somewhere close to the 23 hours last year. I thought it might be helpful to share some of my kit choices - a few have been learned the hard way.

Shoes. Mizuno wave inspires until 50. These have been described as the Subaru of the shoe world. First 50 has a lot of hard pack and road. At halfway I plan to switch to Inov8 Ultra 290s. A bit more grip as the second half is muddy.

Watch. Garmin 910xt. Almost certainly better choices out there but I have this from my tri days. Downside is the 20 hour battery life. I get round this with a USB charger and lead in my 50 mile drop bag. I put it in my bag charging and 30 minutes later it has enough juice to get to the end. It keeps recording while charging.

Map. Harvey maps are great as waterproof and only show a ribbon with the route so only one map for the route.

Jacket. Salmon Bonatti. It gets mixed reviews particularly the lack of breathability. However it kept me dry and warm for the 10 hours of rain last year. Also packs into a pocket and has a hood.

Gillet. Good for dusk when it gets cold but don't need a jacket. Also back up in case it gets very cold.

Spare Base layer in bag. This used to be mandatory and it does get very cold on the Thames.

Hat and buff. Buff passes kit check and helps keep neck warm. Warm hat kept in 50 mile drop bag.

Bag. Ultimate direction SJ2.0 Does the job well and stops me packing too much.

Torch. Petzl NAO is great. It ran out of juice on the A100 so I pack spare batteries and a Petzl Tikka 2 just in case.

Compressport calf guards seem to work for me. I plan to switch to Hilly full length socks at 50 when elephant ankles start.

Body glide seems to work well for me and a small pack will be there from mile 1

A pack of tissues in case it is not just my nose that needs wiping. I also have a spare of shorts or leggings in the bag at all times.

Food. Hi5 gels and a few treats. Centurion food is amazing so not much needed to be carried in addition.

Centurion SDW100 2015 - results analysis


The 2015 SDW100 was won by Peter Kaminsky in 16:50 with Joanna Turner the 204th and last across the line 29:58. I have done some basic analysis on the results to see what I can learn about the race. I hope to attempt the race for the first time this June so need all the help I can get. Fortunately Mark Perkins didn’t run this year as his 14:03 course record would have really messed up my graphs.
I hope to have a crack at a sub-24 result which based on sub-24s at the TP100 and A100 is possible but the SDW has quite a few more ups and downs…

My splits look to be roughly
22.6 miles – 4:00

35.1 miles – 6:40

54.0 miles – 11:00

69.8 miles – 15:15

83.3 miles – 19:15

 
 

I have also included a graph which you can use to get an idea of splits for other times. Look up your target time up on the x-axis and then follow a vertical line up and read off your splits on the y-axis. The climbers.net website also has some great tools to use too with splits per mile calculators etc. I have picked out some points which are close to a sub-24 target time.
Good luck if you are running the race this year. Hopefully I will see you there!

Centurion TP100 - results analysis


I was interested to see how my pacing at the Thames Path 100 compared with others. Did the average runner slow down more or less that I had? All these stats are purely based on the 2015 edition and every race is different... The race was fairly mild for the first 12 hours and then it rained for the last 16 hours. Generally firm under foot and could have been a lot muddier / hotter / colder / drier / more bacon sandwiches etc.

If you don't have time to go through the graphs, the headline stat is...

If you get to 51 miles in about 10 hours and you have a 50% chance of a 24 hour buckle and 75% chance of finishing.

After 30.5 miles, the 24 hour "par" is 5hrs 30. Those getting here after 6:30 hours probably didn't finish.

At Henley, the "par" is just over 10 hours. If you get here in about 11 hours, you are probably going to finish but have missed the 24 hour boat.
 There is a lot of variation around finishing times but if you take 10 runner rolling average (the red line) you can see a trend.
The other thing I looked at was how much do people slow down. A perfectly even pace would mean multiplying the 30.5 mile pace by 3.27 but the average is 4.3 times. The front of the field took 4.1 times their 30.5 mile time and the pack of the pack were more like 4.4-4.6x. The faster runner were also those that slowed down the least.

Where did people DNF (or refuse to continue)? The second half took the bulk of casualties with the 58 - 71 mile stretch getting the most action per mile. Mount Whitchurch is a brute. The hours of darkness take a lot of people. The last 9 miles had a similar rate to first section which I guess is down to the power of the finish line and also the sun was back up for most people.

My splits were 5:24 / 9:34 / 23:03 with a 4.26 multiplier. I am about as average as I could be. My race was the inspiration for this: http://76thmile.blogspot.co.uk/2015/11/how-to-run-100-miles-in-day.html

It is also worth looking at http://climbers.net/race/Thames-Path-100-2012 as they have some nifty stats for this and other Centurion races.

Using Strava labs global heatmap to find places to run

Many people use Strava to record runs and bike rides. Strava has collated all the GPS data points to create an aggregate heat map to show where people train the most. This looks pretty cool but can also help find new places to run.

I was looking for routes for a run in London and the standard map doesn't look too promising. 

However when you add in the run heatmap, you can see a lot of main roads are popular - presumably with run commuters. However Wapping on the right side of the map also glows brightly. Sure enough, there is a nice footpath next to a canal away from traffic.


I was on a trip to New York staying near Wall Street and had a couple of hours free for a run. A quick look on Strava showed the West side of Manhattan by the Hudson River was very popular. There was a cycle path with plenty of space to run. I could probably have found this anyway but it saved me time finding a route. Towards the top of the map, you can see Central Park. It also highlights an athletic track in Brooklyn just below Greenpoint and North of Williamsburg.



I had a look round near where I live, This is an area with lots of great trails including the North Downs Way and the Vanguard Way. Now this is where you can be clever. A bit of spot the difference between the bike and run maps helps find some great trails. The bottom right had corner of the map shows the North Down Way which is a great trail and free of road cyclists and even mountain bikers. It also shows the Titsey Trail and a few other footpaths.

The circuit near the minus sign is  Kenley aerodrome which is popular with cyclists and runners so could be a good place of quiet road training. Parks show up very brightly in run mode - particularly if they host a Parkrun.




It isn't perfect though - the smooth line near the bottom of the map which is apparently popular with runners and not cyclists is the M25 Motorway which is out of bounds to both. Clearly a few runners has left their Strava running for the post run drive home...

Happy trail hunting!

Things I have eaten and drank during races this year

After watching Michael Arnstein's film of running the WSER on just raw fruit and veg https://m.youtube.com/watch?v=QAQJCsrXVKU , it made me think about what I had eaten and drank while running races this year. Only things consumed between gun and finish line count. Needless to say I am not a fruitarian and don't eat like this normally! This was over the course of 226.2 miles of running in the Centurion TP100, A100 and the Vanguard Way marathon.

My strategy with racing has been to grab things quickly in aid stations and start walking with a few things in my hand. This has led to some poor food choices. However I maintain the combo of Maryland cookie, pork pie and coke being the holy trinity of fast medium and slow release foods. I grabbed these at mile 30 of TP100 and viewed it as a stroke of genius.

This is almost certainly not a complete list....

Tea with milk
Coffee with milk
Water
Coke/Pepsi
High 5zero tabs with water
High5 carb drinks
High5 gels (first choice for gels)
GU chomps (like wine gums - not bad)
GU gels (salted caramel good but a bit gooey)
Clif bars (blueberry crisp and choc chip)
Jelly babies
Plain crisps
Cheese sandwich
Ham sandwich
Tunnoch Caramel
Ginger and chilli chocolate (that was a surprise after 79 miles)
Banana
Cherry tomatoes
Pom bear crisps
Mini scotch eggs
Sausage rolls
Pork pie
Pasta bolognese
Chilli con carne
Pasta soup
Maryland cookie (great ultra food)
Whole boiled egg
Vegetable soup
Peanut butter wrap
Gin drizzle cake (thanks Sarah Barker)
Mars bar

How to run 100 miles in a day*

 Or how to run a race and not get lapped by the sun

 Things that are essential to do in the 6 months before you race

- You should be running at least 50 miles a week (lots of 200+ months)
- You need to a follow a training plan
- Pacers and a crew are essential. Use this time to get at least one pacer and ideally at least two crew members
- Don't even think about signing up for the race if you have never run more than 50 miles
- Back to back runs are essential. Ideally you should be aiming for a 50mile / 50 mile weekend and plenty of 35 / 15s if you want to finish, let alone break 24 hours.

I did none of these  in the 6 months before the Centurion TP100

Things I did in the 6 months before 

Started well with a 183 miles in December with bonus miles due to London Bridge being shut so lots of extra commuter running miles.
January - mile 123 of the month was when things went wrong. I slipped trying to turn and run up some steps next to Blackfriars station and fell. Nothing too serious but bent back fingers. I got to work, showered and carried on with my day. A couple of hours later it didn't seem right so went to Guy's hospital urgent care unit. Turns out I had broken my 4 and 5th metacarpal bones in my left hand and required surgery. 14 weeks to go until the start of the TP100.



If you can't run then walk

My normal day involves a lunchtime run so instead I headed out with my arm in a cast and speed walked up and down the Thames with my one arm in a cast and my Garmin on the other one. Two weeks later I was up to 15- 20 mile walking weeks and also the slowest person on Strava. Good miles were sub 14 or so even with tourists on the South bank to avoid. Now if could do another 99 of those I could do a sub 24 hours for 100 miles...

Back in training

After two weeks, I had the big cast taken off and a smaller one put on. I asked the physio about running and he said it would be fine as long as I didn't get the cast and scar wet. Running lunchtimes back on with hand in a cast and the cast in a plastic bag just in case it started to rain. Proper running resumes with a 21 mile week. 10 weeks to go now

Back in proper training

Next 8 weeks was steady training with the three longest runs being two 30 mile runs on the Thames to Richmond and back plus a 28 mile run on the NDW. Now time to taper

Start line -  Zero days to go

So now I am on the start line Aaveraged 30 miles a week for the previous 6 months with a long of 30 miles. Longest run of my life was the Centurion NDW50 (9:58 - see report a bit further down). Surely this had DNF written all over it as I looked at everyone else with their Ultimate direction backpacks and purpose bought drop bags (some people have a strange idea of what "shoe box" size is) at registration. Everyone was talking through plans with their crew and arranging when to meet their pacers.

About 23 hours later

I was arriving across the finish line in 79th place with a shiny "100 miles in a day" Centurion buckle. Miracles do happen.

 So what is my advice?

Clearly I'm not going to recommend breaking your hand in training but there are a few other things which helped me get into the 100 miles in a day club.

There is no shame in walking

There are over a 1,000 members of the Brotherhood of Centurions 1911 and the world record for walking 100 miles is 16:31:38 which would be a very competitive running time. I made sure I put lots of walking breaks in the first 50 miles and most of the last 50 miles was walking. The average pace for a sub 24 100 is about 14 min/mile after allowing for some quick aid station stops. It was very late in the race when my walking / running dropped below this pace despite a lot of walking

Get through aid stations quickly

A typical Centurion race will have to 12-15 aid stations with amazing food and even more amazing volunteers. If you spend 15 minutes in each having a lovely cup of tea while talking to the man dressed as a chicken, you have lost 3-4 hours which is a lot of running to make up. A quick bottle top up, grab some food, make sure you say thanks and be on your way. I always try to get moving quickly but at walking pace to allow my body to digest food. My first few ultras I used a camelbak style bladder but switched to bottles as it is much easier to refill at aid stations. People will also help fill bottles but less willing to do camelbaks. The screw top of the camelbak is easy to cross thread and a lot more complicated than a bottle.

 

Speak to other runners

 It helps pass the time and it is great to find out what other people are up to. It takes your mind off the pain and reduces the risk of getting lost as you have an extra pair of eyes. You might find yourself talking to someone who answered you question about which watch / bag / jacket / shoes / socks / .. you should be using.

 

Mix up training

I had a January goal of a sub 20 minute 5k and sub 90 half marathon. This mixed things up and meant that I had a block of speed work and fitness before starting the slower ultra style high mileage slow weeks. Unfortunately my broken hand stopped things. The broken hand may have been a blessing in disguise as taking two weeks off helped me to recover (no harm having some time off)

Pick up a flattish race with good aid stations

Sub 24 will get you on the podium for Hardrock 100 so not all 100s are equal. The Centurion Thames Path 100 is a fast race on paper but being almost totally flat can lead to you going off too quickly whereas a few hills help to break things up. The T100 is a self supported race so will clearly be trickier as you have to carry you food with you. If you are going without a crew or pacers, I can highly recommend the Centurion races as they have the biggest fields so lots of company for the nighttime and lots of choice for food.

 

Read blogs and books

It helps to read about running. Puts running 100 miles into context.

- Blogs about the race and similar races
Good to know what to expect. Many Centurion blogs out there plus others on Ultrarunning community. I will put a list of my favourites on here shortly.
- Training books
Helps you avoid stupid mistakes. Hal Koerner's one is good.
- Crazy people books
It helps to normalise running 100 miles if you read about someone running across America (James Adams /Marshall Ullrich), Marshall Ullrich's Badwater Quad, Scott Jurek winning WSER on a diet of mung beans and carrots etc.  Also worth watching the "fruitarian" run the WSER only eating raw fruit and veg (lesson - don't eat avocado and dates while running)

 

And finally...

The 76th mile is the hardest. Staying up all night watching a boxset or playing poker gets tiring so trying to stay up all night having run 50+ miles is always going to be tricky. Be prepared for lots of walking and a bit of questioning you sanity but soon enough the sun will come up, your pace will improve and a shiny buckle will be waiting for you shortly.

* I am a pretty good but not amazing runner so a lot of these things will apply if you are chasing a sub 20 finish or 29:59:59. However the sub 24 title sounds better...
