    On the waiting list; and now off the waiting list; and in, for tomorrow. Route.
    Ephemera
    Sunrise 0653 (after we start at 0630); sunset 1953 (as seen from the top of the Mendips??) with the waxing gibbous (87%) moon rising at 1759 to light us home.
    And a bit of off road after the M4, if you want, and also a bit on offer on the Mendips: after Charterhouse at 281km go straight on (ie not left at cross roads) and right fork once on gravel track).

    Your first alternative is ok (gravel track after the M4) but the second is pretty bumpy, if memory serves. And it will be dark.

    Done! And what a cracking route to go with the lovely weather. 327km on the clock.

    Thanks to Marcus and Kirsty for an excellent ride with perfect weather. Enjoyed the Fosse Way gravel section, feeling suitably bold as the gravel got deeper at the NE end.
    After a quick stop to control at Poulton, coinciding with the 9am assembly of about 50 riders from soi disant Performance Cycles, I enjoyed a quiche and a pint of milk from Lidl Amesbury (second control) before cutting through the Woodfords to the lovely Wylye valley, riding the latter in company with a 'fixed rider'. Stopped off to say hello to a friend who lives in Corton on the road NW of Wylye village. Onwards through Sutton Veny, Longbridge Deverill and Maiden Bradley to Alfred's Tower, above the Stourhead estate. I was due to stop for tea with a friend who lives just below the tower when, descending the wooded Kingsettle Hill at speed (?40kph) my front tyre blew (new on for LEL so about 2300km on it, the rear had another 1000 on it from Mille Pennines) and braking on a deflated front tyre didn't do it, and I lost it (together with any memory after the action of braking and keeping as straight as possible). Others in a group mostly from Stonehouse were right behind me and all I remember was being asked if I had a preference between Bath and Yeovil hospitals - I chose Yeovil (and went there by road (thanks to the air ambulance for attending too)). CT Scan and X-rays in A&E etc before transfer to ICU. Two days in ICU was enough - the punctured lung was stable and the various rib and shoulder blade fractures will apparently heal themselves. Discharged Monday evening and now back home generally sore, battered, grazed and weak but will get better. Thanks to my fellow riders for calling the ambulance quickly, for agreeing to let a local (Derrick) take charge of my bike (which is fine apart from a punctured front tyre and a bit of scratching to the Brooks saddle and STIs - but I have not yet seen it - in non-driving/riding mode for a while), and for taking my saddle and top tube bags and GPS off my bike and sending them with me in the ambulance (NB really good practice; they even put one of my glass's lenses in). I hope the my fellow riders were not too delayed on their ride, that my crash did not "spoil [their] ride" and that they enjoyed another 5 hours of excellent riding (we had taken 8:10 for the 200km so far). Sorry to have missed the ride over the Mendips, which would have been in daylight btw (@ransos ). My quest to get to 50 AUK points looks as if it will be unrequited, this year anyway, as I shall be unable to ride for at least a month. Hey ho! When I recover my bike I shall ride the hill and try to see where I came off. When I think of the hills I've been down this year, Alfred's one is pretty innocuous (100m drop in a kilometre).

    That's awful, GWS. As I descended from the tower, a man was standing in the road telling me to stop - it was the paramedic and you were being loaded in as we walked past. I'm not a fan of that descent - overhanging trees, poor surface, poor sight lines and a narrow road make it pretty risky.

    Thanks @ransos and @Dogtrousers . The road west from Alfred's Tower seemed fine to me as I started down it (and I think I've been down there before) and consider I was in complete control, but until I go back I will not be able to make a decent objective assessment. I would like to know what made my tyre go (I was not braking much) and examination of the tube (idc - bike is now with the friend I was going to have tea with) will probably not shed much evidence on that. Hey ho! After 25,000km I guess statistics caught up with me, but I'd much prefer they didn't/hadn't. At least it was early in the month so if I can heal well, who knows if I can't keep the 100s going by a ride in late October :pump:.

    @Ajax Bay

    Glad to hear you're on the mend.

    When I passed you shortly after your 'off' you were still lying in the middle of the road looking the worse for wear !!

    Your ride partners were looking after you as was a friendly local, the ambulance passed me at speed approx. 10 minutes later.

    GWS & hope to see you on the Jaegar Bomb next year ???

    BTW the guys you were riding with passed me on the climb of Charterhouse ..... they were flying !

    @Spartak @ransos @Dogtrousers The sequel - having picked up my bike at last, and examined the evidence.

    Well, exactly one month on from my ‘off’ I have recovered enough to drive. So I took the train up to Bristol/Keynsham to pick up my car (which had been recovered by a friend from the audax start) and then headed down to pick up my bike (which had been in the care of another friend who lives very close to the site of the accident). While there I drove up the hill (it's about 1:10): the scene of the accident - and slowly back down, recognising where my tyre had ‘blown’.
    My posts describing/discussing the accident are here:

    https://www.cyclechat.net/threads/t...challenge-chatzone.95264/page-85#post-4952273
    Apart from the front wheel my bike is relatively unscathed: the (1970s) Brooks ‘Competition’ saddle has been badly scuffed on the left back corner, but remains functional/useable; and the left hand STI is a bit scratched and was twisted in. The inner tube has a major snakebite in it: 11mm on one side and 9mm on the other, which will have caused/allowed the near instantaneous deflation I remember. There is a significant dink in one side of the rim where the puncture was. And there is damage to the left hand rim edge for about a third of the circumference, consistent with the rim attempting to roll on the road surface before saying ‘enough’. There is damage to the tyre sidewall in this area too. Of interest, the tyre had rotated about 20cm round the wheel (ie the maker’s logo was no longer aligned with the valve). I expect this happened when I tried to brake and the tyre gripped more on the road overcoming the friction between it and the rim.

    All this supports my ‘analysis’ that coming down the hill, on the drops (always go on the drops downhill – much ‘stronger’ position and better leverage for braking), fingers lightly on both brakes, I suffered a near instant flat, and, after some immediate (swearing and) braking (which I remember) very shortly afterwards went over the bars landing supine, feet forward, first on my shoulder blade (crack) and that banged in to break ribs, one of which punctured my lung. My head then came down on its left side: the helmet is broken (cracked) and has friction damage. I was unconscious for an undetermined number of minutes. Because of how I fell, the helmet ‘wanted’ to come off: stopped from doing so by the helmet’s underchin strap which cut me and the sidestrap which had a go at my left ear (with a fair bit of blood (ears bleed easily)). This was the only damage to my head (lucky and protected) but my neck got a bit of a bashing – not surface but left/right and up/down stiffness/internal bruising. Substantial bruising (but not grazing) above my shoulder blade suggests I ‘bounced’ on that and serious grazing on my left arm/elbow and left hip suggests that I slid on those two main points till stationary. Other sites of grazing ‘are available’ – all now healed.

    Lucky I was that others were right behind me (and called 999 etc). They thought I had gone down the hill ‘too fast’ (I have this on heresay, third hand) and maybe this is so, but they will not have known that I’d suffered a puncture when descending. Whether this would have altered their judgement I know not. Whether a lesser speed and their riding skills would have allowed them to stay upright in the event of a flat will not be tested, I hope.

    I do not know what caused the snakebite to the Continental tube. The tyre (Michelin Pro4 SC 25-622) was new on before London-Edinburgh-London and so had done about 2300km – I’d expect about 6000km from that make/model of tyre on the front. I had checked my tyres before the ride and the front was at 75psi (5psi more than the graph readout in Jan Heine’s BQ article: actual width 26.7mm, total load 85kg, front 38kg, rear 47kg). It is possible it had lost pressure during the 199km I had ridden. I checked the rear 31 days later: it was at 72spsi (same tyre make/model) - I had inflated it to 90psi before the ride). The road was clear and, having examined the surface by both driving up and down it and walking up and down the stretch where the flat occurred, the surface is good, with no potholes. The side of the road is a bank so I guess the only possibility is a largish stone: the sort of stone you can see and avoid as you ride down hills, I’d like to think. Maybe/clearly not this time.

    What lessons can I learn from this incident?

    1) A ‘fast’ puncture going at speed is likely to cause the rider to crash, especially if any braking or turning is needed.

    2) Don’t apply any front brake (or release it if it’s already being used). Shift weight back to get as much effect from the back brake as possible.

    3) Stay as straight as possible.

    4) Check tyre pressures before each ride. Do a thumb check on each tyre at every stop (well, every couple of hours).

    I have decided that the rim cannot be satisfactorily repaired and since the wheel/hub/spokes (Mavic MA3 on a Tiagra HB-4400) have done 25,000+km, it’s not worth lacing a new rim on. And I'm not sure how much damage has been done to the tyre sidewall so I'm reluctantly retiring that (to the bin) too. I have another similar front wheel: an Ambrosio Excursion rim on a 105 32 spoke hub which now has a new Continental GP 4 Seasons 28-622 tyre on, ready for when I’m able to ride again (hopefully in a fortnight or so). The Brooks saddle is off and being saved for long rides next year and the STI is straightened. All good. Almost off the pain killers now – just using for overnight comfort in an effort to achieve more sleep (still a challenge). Just need the bones to complete their healing, and to regain both mobility and strength in my left arm/shoulder and my neck.

    Some may suggest I’m ‘overthinking’ this accident. But a month off work and 6+ weeks off the bike gives one ample time for overthinking. I hope some may find some of the facts and analysis interesting.

  11. Possibly unreasonably, possibly sensibly, this story has significantly increased my safety paranoia, despite always descending hills extremely slowly and cautiously, and having recently put a new Durano Plus on the front. I think if I had an incident like this then the powers that be (actually power that is, singular) would put an end to my cycling all together.

    You'll be fine. I don't descend either slowly or cautiously, unless the narrowness of the road or the bends warrant it, or if I'm behind someone else going slowly. Ironically (perhaps) at the start of the descent, I had deliberately gone ahead of another rider (who had slowed), thus being at the head of a group of 8 ish, because I don't like going down a hill close behind another rider - they may brake heavily or even crash right in front of you, or something. :whistle:

    Does anyone know if LVIS is running this event this year? I’m shopping around for my first 300. I’ve seen another (Heart of England) from Cirencester which is a little less lumpy, but early in the season for a newbie (April)

    Come down and ride @Ian H 's Old Roads 300 in May. Honiton, Okehampton, Barnstaple, Wiveliscombe, Cheddar and South Petherton (and back to Honiton). Some lovely roads, in May, with an agreeable amount of texture.
    PS I can't find the LVIS 300 on the calendar and anyway, you'll be wanting to do a 300 before September.
